Nokia unveils Lumia 2520: 10.1-inch tablet with Windows RT
- th0br0 13y agoFWIW, it's an 8,000 mAh battery - not an 800 one ;) Anyhow, this tablet looks marvelous. Android would be far more to my liking, but it's still great.
- SEMW 13y agoSlightly off-topic, but: anyone round here know if there's a good reason why are batteries quoted in units of charge (mAh), instead of a unit of energy like Wh or kJ? Seems like it just makes it hard to compare capacities of batteries of different voltages. A 8000mAh laptop battery sounds like it can only store three times the energy of the (2650mAh) cheap NiMH AA battery I have here, but it can actually store 30x, as the AA battery is 1.2V and assuming the laptop battery is 12V (which it may not be, I don't know).
- chrissmeuk 13y agoYes. Amps = current. That means it can sustain 8A of current for an hour. This can be trivially divided into 4A for 2 hours, 2A for 4 hours, 1A for 8 hours etc. Also: 1. It's easy to measure electronically and calculate life from. 2. Isn't a derived non-linear figure like a Watt i.e. P=IV and voltage declines over a time on batteries making it a whole shitload of calculus and other nasty stuff. 3. Joules are hard to quantify as they are a measure of energy and not current.
- fleitz 13y agomAh is measured at 1V at 1 Ohm. So yes, your 8000mAh stores 3X as much as the 2650 mAh battery.
- pjc50 13y agoNo, it's measured at the battery voltage (which is usually not 1V, and varies with discharge) It's measured this way so you can most easily estimate runtime by putting an ammeter in series with the battery.
- tobiasu 13y agoNo way. I have no idea how mAh are measured in a lab, but they are certainly not in relation to 1V. To get Wh, multiply by voltage. 2.6Ah * 1.2V = 3.1Wh. 8Ah * 4V (one cell is my assumption) = 32Wh. The battery has 10x the capacity of a NiMH (that's the lower limit, it could have two cells but that seems a bit excessive for such a device). Other than the battery discussion, Nokia devices running RT are about as interesting as the dirt on my shoes.
- yread 13y agoBecause you (well, maybe not you, certainly not me, but perhaps some people) should be able to deduce the voltage from chemistry of the battery. So all LiIon LiMnO2 chemistry batteries have 3 V, LiFePO4 chemistry has 3.2 V. Then you can just multiply the voltage by mAh and you have energy in mWh
- Scene_Cast2 13y agoThe problem with this is two-fold. First - I shouldn't have to care about battery chemistry. Second - what if they're wired up in series [1]? From personal experience, I've seen that laptop & mobile batteries list watt-hours as well. I'd prefer if that number was advertised instead. [1]With two LiPo 3.7V 3Ah cells, you can have either 7.4V 3Ah or 3.7V 6Ah.
- underwater 13y ago@chrissmeuk, you've been hellbanned.
- reportingsjr 13y agoThey rate them in volts and mAh, because depending on how quickly you take energy out of the battery you can end up with more or less total battery capacity (and while the mAh rating will change as well it won't change as much as the Wh rating).
- seanmcdirmid 13y agoThat is one good looking tablet! I wonder if the keyboard is lap-able? I think its a great idea to put the battery in the keyboard cover so it can counter the weight of the tablet more easily!
- edandersen 13y agoThis looks fantastic, especially if you can actually use the keyboard on your lap without it flapping about like a Surface.
- innino 13y agoLooks lovely. I would be really interested to own one of these if I had the money to buy surplus devices at the moment. Trying to see how using it solely vs an iPad would be interesting, 8.1 is clearly the more capable mobile OS but I wonder whether the iPad's superior app store would clinch it regardless. Versus an Android tablet would also be interesting. Maybe it's time for the tech sites to do some really thorough usage comparisons...
- iamshs 13y ago[Edit : Also released today: $339 for 6-inch Nokia 1320 [1,2]. Now that does not pinch the pocket at all. ] That tablet is a beauty. Nokia's industrial design team deserves kudos for putting so many beautiful products on the table. It also has 16 hrs battery life with cover attached. Impressive. Any video of it?

- JanezStupar 13y agoIt's a tablet. And its a post iPad tablet. I fail to see what is so impressive about it.
- RyanZAG 13y agoHow does this compare to Surface, and why would anybody buy one of these instead of Surface? With Nokia now owned by Microsoft, does this not mean that Microsoft has released two Windows RT tablets with similar stats? I assume Microsoft will merge the two products in future?
- iamshs 13y agoDifference seems processor, color options, and keyboard usage functionality. I assume MS would develop Lumia line having its own tablets, otherwise it does not make sense to release sole Lumia tablet and then shutter the line down in future, when they did have the choice of not releasing at all.
- pavlov 13y agoTechnically Nokia isn't yet owned by Microsoft. The Nokia board has recommended the sale, but it's not done yet. There's always the tiny possibility that the merger won't be accepted by the Nokia shareholder meeting (which is next week, IIRC).
- Touche 13y agoMicrosoft didn't release this and in fact Microsoft can't legally influence Nokia in any way until the sale has been approved by all relevant governments.
- chiph 13y agoGiven the physical design of this vs. the Surface RT, I'd take the Nokia in a second. The reality is, with umpteen-thousand RTs clogging the Microsoft warehouse, that'll be what they try and push.
- bryanlarsen 13y agoThis one has LTE; Surface LTE is just rumours at this point, AFAICT.
- _random_ 13y agoLooks really well-made! And the new smartphones are on par as well!
- chrissmeuk 13y agoExcuse the rant, but I'd buy this tomorrow, if only one thing was fixed: There was a proper RT version of Office rather than a hacked up desktop version. The desktop version is simply shit on an RT tablet. I tried it. It's horrid. It's slow and fiddly. It's only ok if you have a keyboard attached, know how to use it only on a keyboard and have magnfiying glasses strapped to your face. The hardware looks awesome, as other Lumia kit is (I own an 820 and rather like it) and Windows 8 is pretty good on a tablet from my experience (despite naysayers) but FGS Microsoft please sort out office. Oh and please can I have a stylus for OneNote.
- johnpowell 13y agoI looks lovely but I wish a better name was chosen. It reminds me of the Performa 6214 I bought in high school. You couldn't really talk about it since the name was nonsense.
- Aardwolf 13y agoIt looks like a laptop, does the word "tablet" not mean anything anymore?
- pavlov 13y agoThe base unit is a flat tablet that looks essentially like a Lumia phone stretched out to a 10" diagonal. The keyboard cover is an optional add-on. It seems more useful than most tablet keyboards because it also has an extra battery, bringing the unit's total battery life to 16 hours.
- Touche 13y agoA tablet is a computer with a touchscreen that can be carried around and doesn't require the use of a keyboard. This seems to fit, no?
- ZanyProgrammer 13y agoLooks like this will be vapormgware.
- theboywho 13y agoI think this is the worst day to release a new tablet. You end up directly challenging the new iPad to be announced.
- josefresco 13y agoOr, people so thirsty for tablet news will eat up an announcement like this all morning until the folks on the west coast roll out of bed to hold their event. Granted after that event your tablet announcement gets thoroughly buried, but it's better than releasing it in the 2 weeks after the Apple event when they dominate the tech news.
- bruceboughton 13y agoI really don't understand why they have reused the Lumia brand. Do they really think people are going to talk about the products using the number? You can walk into an Apple store and talk about their products more or less like a human being: iPhone, iPad, Mac Book, iMac, iPod, etc. Can you imagine walking into a hypothetical Nokia store and trying to get your head round the differences between the 1320, 2520, etc.?
- josefresco 13y agoPeople walk into BMW dealerships and wrap their heads around the 3 series, the 4 series, the 5, and 7 series etc. Each with their own confusing combinations of models numbers (535xi etc.) And BMW is even making it harder for folks with the new-ish even models (4, and 6 series). If you hammer it over consumers heads long enough, people will learn your crazy naming schemes. I don't think Nokia has that kind of time.
- bruceboughton 13y agoYes, but the 3-series, 5-series and 7-series are all cars. In particular, they are luxury cars of increasing size available in saloon/estate versions. The Lumia 7879 tablet and Lumia 347334 smartphone are different things and 347334 > 7879 does not hold, or make any sense.
- iamshs 13y agoNokia's lines have always been segmented like this. See N-series or phones like 1100, 3210, 5610 etc. These tell the affordability and luxury "rating" of the phone. Some 6-7 years back when I was purchasing my phone, I had a budget hence knew which series would be affordable to me. (Albeit I settled on an abomination of a phone like 3250) Although I concur Apple has the best approach definitely.
- xerophtye 13y agoActually, traditionally people have always talked about Nokia phones in terms of numbers. 6300, 3310, 1200, 1208, N95... Sure it's kinda difficult for new comers etc, but i guess at one point Nokia was big enough to have the luxury of everyone knowing their products by numbers. Though, as you point out, they should consider a better nomenclature, especially now that they aren't that prevalent anymore.
- Fundlab 13y agoSadly in the USA its sale has been tied to Verizon and AT&T. I would love to snag one for TMobile, SimpleMobile or MetroPCS. Headup if anyone knows how I can get one with being locked unto those twin devil networks
- seanmcdirmid 13y agoSubmit seems to have been flag. Is hackernews really that anti Microsoft? Or is engadget now about link spam? Disclosure: I work for Microsoft and my wife works for Nokia. So ya, ouch.
- throwawaykf 13y agoWhile I don't think Engadget is that good anymore, this was still original reporting, and not too far below par for the course for this kind of story. (Compare with the Verge counterpart: http://www.theverge.com/2013/10/22/4865306/nokia-lumia-2520-windows-tablet-announced/in/4629721 http://www.theverge.com/2013/10/22/4865306/nokia-lumia-2520-...) I'd go with your other theory (https://news.ycombinator.com/item?id=6591687 https://news.ycombinator.com/item?id=6591687)
- Toshio 13y agoOr perhaps it could just be that we find anything made by microsoft mind-numbingly uninteresting. Just like anything made by SAP, IBM, Oracle, CA and other old-guard tech companies. Seriously, why are there e.g. no SAP employees on HN wondering whether HN is really that anti SAP?
- freehunter 13y agoIs "I don't find this article interesting" a good reason to flag? If it got to the front page, people must have found it interesting. It seems like flagging would mean "this article does not belong on HN". I think the announcement of new phones and tablets in new form factors with new apps and an upcoming software update from Nokia would be relevant, moreso than a slightly thinner iPad with the same internals and software as the already released iPhone 5s, which will undoubtedly be filling the front page later today.
