The Aceeca link introduced in this thread got me thinking. Got me looking around. I've noticed quite a bit of "other" stuff being made for industrial, corporate, military, and other specialized uses. Most of the customers are themselves large-scale device manufacturers who market custom-sector machines which compete against PDAs. I've just ordered two of the most expensive parts I'll need: a Toradex Colibri PXA320 IT mainboard and a Sharp 4.20" XGA (1024x768x24-bit) touchscreen LCM. Gonna build my own fancy (PDA-based) mobile computer. Forget about the underpowered half-crippled toys that HP, Dell, Apple, Sony, Toshiba, Palm and all the rest want me to buy. It's all junk. And it's cheaper this way, too. I'm all set to go and still a little bit vague on exactly what I'm building ... but the mainboard only measures 67.6 x 36.7 x 5.2mm and the LCM is only 4.2" ... I might be able to squeeze it into a large PDA casing. Probably not though, if I want to pack the twin SD slots, twin CF slots, RS232, twin USB hosts, biggish battery, and all the rest in there. I suppose the 806MHz PXA320, 256MB DDR2 RAM, 1024MB Flash ROM and all the rest might produce a little bit of heat, too. Hey, at least it comes pre-installed with WinCE 5.0 or my choice of linux flavours.
