I currently have a Kyocera 7135
http://www.kyocera-wireless.com/7135-smartphone/ I use it as PDA (Palm 4), as music player (MP3 on a cheap 256 Mo) and phone. It's a little huge, and batterie get the job for a full day.
What I think may be the next iPod killer:
Software:
-Easy note taker with screen drawing (not bulshit caracter writing, too much CPU intensive and slow, just like the Monet appz for palm)
-iCal entery (just click and enter a graphic draw)
-phone, can connect to internet with high speed (3G or satellite) and adress book check
-can see my incoming e-mail (check every 15-30 min so it safe batteries)
-listen to music
-photo check
-a calculator touch screen (a scientific one!, by the way it's totaly a missing widget what I'm suppose to do with a calculator that can't even do a square root?!).
Hardware:
-High capacity hydrogen cell fuel batteries (sorry for my poor english) or any long lasting batteries (replaceable! god d..m it)
-Hard drive base (10Go-20Go is enough reduce the size!)
-touch screen (graph draw)
-phone buton on touch screen (save space)
-the click wheel to navigate the interface
-small size
-Use it as your internet modem at home or on the road! internet through wireless inside this (total mobility finally, I can do it my Kyocera but it cost a lot of money, I use it only when really require currently)
Give me that for under 1000$ and I will be the first in the row to buy this little baby and throw away my Kyocera 7135. That in my mind the best thing that could happen, but it require to have the carrier and Apple working together. Snif snif...will not happen.
