Re: Debian GNU/Linux on tablet hardware

Hello Luke

No really build it myself.

First, we need a prototype to develop our software on it. The proto can be any 
ARM based card plugged to a screen. We're currently playing with a beagleboard 
and an igep 0020 card. We can can plug an USB wifi and a USB IR receiver to 
play with (may be a home theater remote like this [1]).

Then, we'd need to field test our device. This could be done with netbooks or 
small tablets, but not with a bunch of boards and wires ;-) . We'd need ~ 10 
of them to lend to family and neighbours and get feedbacks.

Once this is done, we'll need a small serie (~ 100 depending on price) to 
really get serious. 

Regarding the device, we'd need something quite standard. The screen should be 
at least 800x600. Bigger would be better, but the device price for the small 
serie will be the main limiting factor.

Regarding user input, I'm wondering if a touchscreen would not be better than 
buttons behind the frame. Navigating in a menus with these rear buttons is not 
user friendly. But buttons are needed in case customer loose the remote 
control. May be a touchscreen as a fallback is better for users. Still 
scratching head there.

That would be better: I've not done HW design for a while (~ 20 years).

All the best
