-Touchscreen is awesome
-SD card attachment of up to 32 GB
-Behind the times
-Video playback doesn't use all of the screen (not true widescreen)
Old, yes, since I've had it nearly three years, but it does what I need it to do. From what I've seen, newer phones kinda suck.
Can connect via USB
Not too big or too small.
Can survive motorbike crashes (My ex had one)
Needs a better quality camera.
Internet browser has blocks (I blame t-mobile)
Lacks the awesome games that Nokia has.
I agree with Darkish on...
Touch screen and slider for a full QWERTY keypad
Large app market
Easy for texting
Fast web browser
Google search with speech
Syncs with email
And a few of my own...
Includes an app that allows for you to "kill" apps to save battery life
Easily portable while still possessing all the quality pros stated above
Shorter battery life than the average phone (I tend to require a daily charge)
Poor camera placement (often find my finger sneaking into a couple photos)
Poor button placement (Buttons on the sides are accidentally pressed at times)
full qwerty keyboard
easy to manage SMS/emails
GPS without having to go online
Can withstand falls
Screen lights up/buttons blink when I'm about to receive a call
Easy to transfer files
Not as many (working) applications as I'd like
The only thing I would say for both is that they need better quality camera, especially the Nokia E71. Other than that, I'm really happy with the both of them. Qwerty keyboards ftw!
