Pro: - 1600p matte display looks amazing - proper support for S3, very low S3 power consumption - super quiet, I never hear the fan and the laptop is never uncomfortably hot (even doing heavy things like compiling buildroot) - amazing performance for a laptop (5850U) Con: - no SD card reader (seriously, why?) - proprietary dongle for Ethernet - Ethernet is only GigE - Came with MediaTek 7961 WiFi, which while supported by mainline Linux, the performance is trash (~30MBit on 802.11ac). Luckily it's only M.2 so you can replace it with something like the AX201

  > matte display is great I thought we moved past whatever technical limitation it was that required matte surfaces on flat displays? It's like having Vaseline smeared on the screen, diffusing all the colour - why would you actively want that?
  - sdflhasjd 5y ago
    It's the other way around, I think, there are technological challenges to using Matt coatings The issue is, like you said, the smearing and contrast, which was a bigger issue with newer, high DPI displays. That being said, I do believe there are solutions - I have used 4k Matt displays that don't have the aforementioned issue, I think most glossy displays are there for there as a form over function thing. Glossy displays are still annoyingly reflective and good antiglare coatings are exceedingly easy to damage
    - sgt 5y ago
      I disagree with that. Take a look at MacBooks for example - excellent screens that are glossy but not very reflective. Never seen anything better on a laptop.
      - nvarsj 5y ago
        Have you ever tried working outdoors on a glossy screen? You will wish very fast it was matte.
        sgt 5y ago
        If by outdoors you mean coffee shops and so on, it's fine. But yeah in the open it is bad, like most cell phones etc. I don't consider that a common use case. If you do field work, get some shade behind/over you. Plenty of reasons for that.
  - tjoff 5y ago
    The only technical limitation we have is that matte displays collect dust etc. so they are not suitable for touch-devices. Why some manufacturers would want to use glossy on any non-touch device is beyond me.

The Framework laptop has the best idea, IMHO. It just gives you a bunch of USB-C ports, and enhanced "dongles" that are designed to be physically secured to the case rather than dangling from it - hence avoiding wear on the ports themselves.
- dotancohen 5y ago
  Great idea, but the cost in space and weight is not insignificant. I really hope that future Frameworks package things a bit better, I would even forgoe the USB-C connector for a smaller proprietary connector (I feel disgusting saying that) as the modules are not meant to be used elsewhere. They could still use USB-C signalling under the hood. Is there any movement for a smaller standardized connector? Even small phones could benefit.
  - zozbot234 5y ago
    USB-C goes to great lengths already to minimize "space and weight" costs. The easiest way to address those would be introducing "modules" that provide multiple ports when practical in the space that's designed for a single connector. Smaller designs though would inherently be more fragile.
  - Steltek 5y ago
    USB-C is a standard and would be better understood by 3rd parties than a custom connector developed in-house. I hope the physical form factor for Framework's modules/adapters becomes a standard in itself because I think it would essentially solve the dongle problem for everyone.
  - Rebelgecko 5y ago
    If you're worried about the weight and don't mind how it affects the looks, you could just leave the dongles unplugged and use the recessed USB-C ports

  They recently started selling in some EU countries, but not yet in the one I reside (NL). It contains an Intel 11xxx, while 12xxx (Alder Lake) is vastly more superior and also there's no AMD option (5 nm ARM like M1 would also be very power efficient). That said, it is a great first iteration. I wonder if it could pass QubesOS certification?

According to the hardware maintenance manual: "Wireless LAN card (for selected AMD models)" [1] I can confirm from the internal photos I have of my X13 AMD Gen 2 (I swapped the stock SSD for a SK Hynix P31 Gold 1TB) that the WiFi is indeed M.2 socketed.

    Huh, you are absolutely right, my MT7961 is M.2 too. I too have swapped my SSD but I guess I didn't look at the WiFi chip at the time because I "knew" it was soldered. I was originally looking to buy one of the X13 Gen 2 Intel models that have it soldered, I must've thought it applied to AMD as well. I guess I'll try out Intel AX210 then, to see which one actually works better for me.

  i dont think they do it on these models. i have an AMD Ryzen Pro Gen2 P14s and replaced the wifi+bluetooth M2 card with an AX210. the mediatek card was garbage; not just slow (ping times were 3x normal), but caused my machine to insta-reboot under git clone of a large repo in Windows 10, and simply dropped the wifi link in Manjaro during same op, so it's unlikely to be driver related. kinda bizarre that they don't offer this card as an option on AMD builds and force mediatek upon you. the AX210 is a great card which supports monitor mode & packet injection.
- WesolyKubeczek 5y ago
  In newer models they stopped doing that (xx50 and up, I thing). Must have been relaxing of some FCC requirements or something. Previously I've read that this whitelisting was due to the fact FCC would certify the laptop with the particular adapter as a whole, and replacing the wifi/wwan adapter, or adding WWAN where there wasn't one, would make the whole device "uncertified".

      2.5GbE is relatively common in gaming laptops: https://geizhals.de/?cat=nb&xf=31_LAN25g https://geizhals.de/?cat=nb&xf=31_LAN25g I own a GPD Pocket 3 which has it: https://gpd.hk/gpdpocket3 https://gpd.hk/gpdpocket3 And 10GbE is basically limited to the MSI Katana: https://geizhals.de/?cat=nb&xf=31_LAN10g https://geizhals.de/?cat=nb&xf=31_LAN10g
- paulmd 5y ago
  There has been a sea change on this in the last year or so. 2.5gbe is really starting to hit the market in a big way, multi-gig has gone from "why would you need that" to "in systems by default", and it did it all of a sudden. I did a mITX build on a B550 board last summer (so, not the super premium high-end boards) and all of the options I was looking at had 2.5gbe ethernet. Going forward, both AMD and Intel have built 2.5 gbe controllers into their cpus and chipsets, so if partners want to use it, it's there. As such you will see it start to be rolled out even in consumer products over the next couple years. The initial rollout was hampered by a few "light errata" with intel's controller implementation (basically it didn't work at 2.5 gbit speeds at all, oops) but we're a couple gens into it now and it's going forward. AMD has one on their chips as well (if not faster, I want to say AMD has 10gbe in their dies for Ryzen Embedded usage). (expecting it in a 2020-era product, however, is perhaps not reasonable, like I said this is something that has changed mostly in the last year or so. Although granted a Thinkpad is not a consumer product so maybe it should have been ahead of the curve. But I don't think multigig had penetrated even professional spaces that well in 2020, except perhaps 10gbe in certain high-end segments.) The gotcha with multi-gig has always been switches, very few cheap switches existed and the ones that did were mostly SFP+ and not 10GBase-T (i.e. you either need new wiring anyway, or you pay $50 a set for SFP+ adapters). This is somewhat better with 2.5gbe, there are now some 8-port switches under $200, but it's still a long way from 1gbe where you can get a nice 8-port for like $25. Hopefully it is a matter of volume and prices come down over time. I'm a little miffed that 10gbe got passed over - 2.5gbe seems like a half-measure, and the wiring argument isn't very compelling to me. If they implemented 10gbe you could always allow fallback to 2.5gbe if that's what the signal quality can support (many <10 meter Cat5e runs are good enough for full 10gbe anyway) and it's a much more significant step than 1->2.5gbit. And the economy of scale here is significant, if consumer stuff goes 2.5 then that's what gets made and 10gbit remains expensive. Anyway currently I am eyeballing the Netgear MS510TXM - this does pretty much what I want in terms of giving me a few SFP ports for fiber links (or server usage - SFP does have lower latency), a few 10gbase-T links for consumer PCs with Aquantia 10gbit nics, and a few 2.5 gbit ports for consumer junk. At $500 it would be nice if it was a 12-port, but it checks most of the boxes at least.
