After reading Treo vs Blackberry, I was sitting around thinking what the perfect phones features would be and this is what i came up with for hardware
CDMA/GSM
Camera
Gps
Wifi
keyboard of the curve
plus touchscreen of the treo
Treos programmable keys around trackball
two speaker from the curve instead of one (with the cutout holes)
SD slot from ipaq or psp
i think they could also get a bigger screen on a curve sized frame with a few tweeks
and upgradable onboard memory
that really all i can think of right now. please add your dream features you would like to see
