Question: Gemini or GPD-Win2?
Hmmmm..........that's a good question....
Having had the original WIN prior to the Pocket, I can relate to the WIN 2 even though I haven't seen it in person.
From photo, it's clear the keyboard and keys are much better size-wise than original WIN. However, don't know how the keypress on the keys will feel. Looks similar style (though larger...) to the ol' Nokia N900 I had...so, probably clicky type keypress.
I have no need for the WIN gaming controls, so, not a plus for me.
For me, think Gemini keyboard would be the better choice.
Other key question in decision to me is OS choices. Do you need/want Win10? If yes, then WIN 2 is your choice. If not, then tougher choice again as both can run Linux.
If you need/want Android, then you'd probably go with Gemini. I don't like Android for various reasons, but Gemini can run Linux, so, that's good.
Both are quite pocketable, with WIN 2 slightly smaller, but also bit smaller display. Found the WIN display very good and sharp though.
As you can see, there are some advantages for each...just depends in the end what's most important features for you....
Just my 2 cents...
