Well, as I'm selling and using the Gemini myself, I can tell you a few things about it:
1. It's good to use on the table, but not in your hand. It opens up to a fixed position (which isn't a very good one) and it actually wears out. I'm lying in my bed now and have to hold the screen while typing, otherwise it would close itself.
2. The keyboard is... well, not that great. It would be good if the keys all reacted well, but often while typing faster, a keypress isn't recognized, so you're pretty slow.
3. Typing in the dark is almost impossible (due to missing keyboard backlight)
4. It's great for Android - but don't expect to use it for Linux. It's not really optimized and struggles to run at the high resolution the screen has. LibreOffice runs incredibly slow - it's not usable. It runs a LOT faster on the Pyra.
It's a cool device, I use it as a smartphone (as it has a keyboard built-in), but I wouldn't want to use it to type longer texts.
About outdated specs of the Pyra:
Hm, I'm not that sure about it, actually. Yes, high-class smartphones have SoCs that are a lot faster.
But not mid-class or cheap smartphones.
But each time I check out what SoCs are available (for a possible upgrade), they often aren't really an upgrade speedwise. Yes, they use less power for the same tasks, but speedwise, the A15 was pretty good.
and commodore minutemen/women out there!
