I have used many phones but this is the worst ever. Main thing is its usability and software design.Actually this software was not designed for a phone. This software was for hand held PDAs which is now being used in Windows based phones. It has plenty of buttons on hardware but anything on the screen is just plain BAD.You cannot use this phone with fingers. You have to have stylus to use the phone screen. I cant take the stylus out every time if I have to use it. You need two hands to operate the screen.This software interface is decade old and cannot compete with new software designs. I dont recommend it.
