I'm with the parent. Driving a 4K display is really power hungry and the advantages are basically zero if you are using a 16 point font anyway. I'm 1980x1080 on a 13" laptop display. If I've got my math right, that's 169 dpi. A point is 1/72", which gives me 2.35 dots per point, or about 37 pixels of height for a 16 point font. With anti-aliasing, that's absolutely fine for readability.
If I had a monitor that was twice the size (reasonable on a desktop), I'd be looking for 4K. Or potentially if I wanted 8 pt fonts to be shaped nicely... But of course, I couldn't read them anyway on my display... Anyway, on a mobile platform (what the original article is talking about), 4K is a bit of a loser unless you have super eyes, IMHO.
- mixmastamyk 7y ago13" is tiny for getting work done, I suppose it hd makes sense there. I have a 15 and 20", and 4k makes it tolerable.
- mikekchar 7y ago13" laptop fits in a handbag (it's A4 sized) and mine weighs 800 grams. I get 8-10 hours of real web development (with Docker, emacs, Firefox) on a single charge (I'm often without power for the entire day). Again... mobile :-) If you just want a luggable, then 4K can be a reasonable option -- especially if work is paying for it. However, for the extremely nomadic work style that I have 1080p, big battery is way better.
- 867-5309 7y agomay I ask which model laptop you use? 8-10hrs at 1080p is very good. I get 6-8hrs on an Intel N3060 at 720p, but that's not great for development.
- mikekchar 7y agoI posted this in the sibling post, but I'll copy it here: It's a GZ73/NL-NRA https://dynabook.com/direct/onyx-blue-pgz73nl-nra.html https://dynabook.com/direct/onyx-blue-pgz73nl-nra.html Actually, I was mistaken. It's 859 grams :-) That includes the battery. This particular model has only a 256 gig drive on it, though. I should also point out that it's an Intel box. I'm impatiently waiting for an AMD box with similar battery performance. I should also say that I use Arch Linux with i3, powertop settings and set my backlight down to about 7% to get the longest battery settings. This is fine indoors, but if I'm working outdoors or in a sunny place, I'll have to up the backlight which will cut a couple of hours off the peak performance.
- 867-5309 7y agomany thanks, impressive stuff
- kingosticks 7y agoIs that 800g with a battery in it?! What laptop is this?

- 867-5309 7y agothanks, very impressive. if only it were available to buy ><
- kingosticks 7y agoditto! I'm off to Japan in a couple of months, I'll try and come back ~859g heavier!
- mikekchar 7y agoI don't understand why they don't sell it elsewhere. It was the same with the previous model I bought. You've got a full power, A4 sized, < 1kg laptop that gives you a full day's work on a charge. How can they not sell that? And eventually Toshiba decided they had to exit the laptop market because they couldn't make any money at it... It's baffling.
- 867-5309 7y agoit's rare enough to find an i7-8th gen in anything without a >=15" screen and keyboard with numpad. Dell Ultrabooks perhaps but they start at 1.2kg AFAICS
