I love this phone! It is slim enough to fit in the pocket of my jeans and durable enough to withstand being dropped. It also has larger buttons than phones such as a Treo or Blackberry, which is great for those of us who are not that adept at sending text messages.
The color display on the handset is easy to read, though some of the commands are not very intuitive to use and you will probably have to consult the manual. Among it's features, the phone has a camera, Internet and the option for Bluetooth.
I love the clamshell design, since it keeps you from calling people by accident. However, the display panel on the front still lets you see who is calling you, and you can even add a wallpaper image to this window.
I highly recommend this phone, although it can be expensive.
