It's an interesting idea. GPD makes machines that will appeal to those interested in handheld gaming and those on pager duty.

I own devices from GPD, and I have had two issues -- devices are simply not reliable, in just over a year the screen showed a green verticle line, and the display died a few months later. Secondly, the keyboard is simply unusable if you plan to program on it.

Which version of the GPD did you have? Maybe they've improved it since then.
