Sure, I'm not saying we ought ot do it, but some third party might. My point is - are *we* to use these prototypes for anything ? I don't use my Gta02 due to
its lack of features, like battery life - only use it as a GPS.

So why not making this a bit more attractive to hackers by changing some parts of the design ? For example, changing CPU and display driver. And maybe add some
room inside for attaching a custom small PCB (we should have a bit of space right now). I'd like to have a WPAN module inside the case, for example. Don't
mention USB please, it's not practical.

True. But we can start layout with what we have, or cannot we ?

If you are referring to software, yes. But hardware is closed.

My worries are design becoming so obsolete that it does not fit any concrete purpose. Like designing an open hardware vacuum-tube television. It's fun, but
won't fit any practical use.

Heh :) That's why I decided to buy one, and not build my own :P
