I actually have this idea in my head, have for awhile now.
Searched round for touchscreen info, and this thread popped up.
Strange how its almost exactly what I am envisioning.
problems such as finding an LCD that fits properly, are proving to be the hard part.
Scrapping together various iBook and Powerbook external and internal parts, would be where the casing, logicboard, ports, video out, RAM, HDD, battery, airport could come from. Id forgo an optical drive for space concerns.
Figuring out how to get the correct dimensions is difficult.
First, id want the size to be about 100% the same as a laptop keyboard. As the picture shows. But finding an LCD screen that is the same size, thats a problem. Width, not so much, but height is very difficult.
The point of me doing this is to basically drop the touchpad, going with touchscreen, drop the optical, and shrink the whole form factor. I think it could be done, if only a screen that fit "good enough" could be found....
