Hmmm....Lovely...Looks Lovely.
I have to say though, some of your suggestions are rather unreasonable (If not expensive).Now, I know these are general suggestions, but Wifi, bluetooth 2 CF, 1 SD all in one device? I can't really see that coming any time soon.
My suggestion is, make a cross between the Axim x50v and the C3000....A clamshell device with a lot of power...But this is a mere wishlist.One must research and make the best compromise between power, design, and battery life.Mabye someone could come up with a list that's more specific (Meaning...CPU:Intel Xscale pxa27x @ 312-624 mhz, and so on.), but not unreasonable(And cost efficient).Mabye then, a contracted manufacturer could make these devices...And a reseller could sell them, but only with the right demand.
One more, IBM and several other companies have made PDA reference designs, ready for take-off.Mabye, with a little tweaking, something could be done.Check out
www.linuxdevices.com in their PDA section for more on this matter.
