Overall I’m very interested in ARM Linux laptops with good battery & keyboard, but even 10” is too small, so I don’t think Libretto form factor is interesting to me.
> Display: 7.8 inch eInk display, 300 PPI. 5 finger touchscreen.
I think this idea is cute, but I’m markedly less productive under 16” of screen; and working below 12” is out of the question for me. I’d prefer a 12.5” - 14” form factor. If you can squeeze the bezels these screen size can still be extremely portable!
I did a lot of Chromebook RDP to desktop in college (best performing $700 total computing platform for a student) on a 10”, and found I worked at about half the speed on tasks that required research. There’s less of a penalty if you’re strictly writing stuff down.
Likewise with screen technology. I’ve yet to use an ePaper display that wasn’t the worst part of a device. I have friends who are frustrated with reMarkable 2; will your display be better than reMarkable?
> CPU: 2 (2.2 GHz Kryo 660 Gold – Cortex-A78) + 6 (1.7 GHz Kryo 660 Silver – Cortex-A55)
This is fine for me!
> GPU: Adreno 619
This is fine for me
> RAM: 4 GB LDDR4X but ideally min. 16 GB
If you are buying a SoC part instead of motherboard RAM, would it be tricky to get to 16GB without increasing the CPU part?
Anyways more is always better.
> Connectivity: 5G/LTE, BT 5.2
I am okay with BT feathering to my phone, but I haven’t used a laptop with wireless internet in 10 years so maybe there’s a special joy to it.
> Battery: 137.7 mAh, hit 144 hours on 115mAh set-up on intensive drain cycle in browser, no optimization for battery implemented OS-side yet. Just long enough so you also can rest on the 7th day.
This sounds great, thanks to the ultra low power display.
> Typing: 60% keyboard with Cherry switches, low-profile
This is probably the most interesting part of your list to me. An excellent keyboard will distinguish your device from Pinebook Pro and other low power ARM notebooks. Right now mechanical laptop keyboards are very focused on gaming.
Given the hacker community love for classic X series thinkpad design, I’m surprised no one is re-targeting that design with ARM components and vastly simplified internal architecture.
