I agree with the author of this post. The iPod edges close and close and close to a PDA. Cellphones edge close and closer to iPods....and are already PDAs. Hell, my PDA had an MP3 player years ago.
And while there's something to be said for discrete devices (same argument as agains all-in-one printer/scannner/fax combos....with separate devices you don't lose ALL the functions if one ofthem breaks) there should still be quite a market for an all-in-one device. It's not like it'd be hard to create; in fact, they have made them....merge the Palm Treo smartphone with the large screen and hard drive of the Palm LifeDrive and you have the ultimate iPod/PDA/Video+StillCamera/Cellphone/ combo.
Then have a 12" iBook verison of it for the tablet/eBook crowd.
Hopefully one day with a roll-out flexible OLED screen.
And best of all....one designed and made by Apple for the absolute best out-of-box experience.
