My old Motorola Q9H on the left, the new Nokia E71 on the right...this phone is TINY.
It has 3G, Wifi, GPS and it doesnt even make a dent in my pocket.
The Symbian OS is extremely quick and getting around the phone is a breeze.
It took me all of 2 minutes to setup exchange on the phone. The only negative things I can say is the keyboard is cramped but I expected this since its such a small phone. If you have large fingers like it me, it may take some time to get used to the keyboard. The screen is bright and clear, the speakerphone is good, and the call quality is what you've come to expect from Nokia's, exceptional.
