First, I want to say, this is my first Symbian OS phone and it has it's issues. The UI is not as intuitive as an iPhone for example. There were several times I had to read the Help guide in order to figure out how to do some relatively easy things (like adding a non-predefined shortcut to an App onto the home screen). There are fewer apps available for Symbian and there's no SD memory slot. However, once you get used to navigating the Symbian OS's settings screens and get the 3 home screens setup the way you want, this phone cannot be beat. It is relatively quick, the switching between 3G and WiFi is flawless, the calls sound great, the video quality is the best I've ever seen on a phone (try uploading a digital copy of a blu-ray movie) and the keyboard is a joy to type on. Battery life is better than most and the 16 gig memory is sufficient. The Exchange integration is excellent and the OVI maps are awesome (The Trip Advisor integration is a nice touch too). It feels solid and looks great. After using various Android phones and an iPhone 4, I have to say this phone has them beat by far. Yes, there are some things that Android phones or iPhones do better, but overall, feature for feature, this phone is simply the best smartphone on the market at this time. If you want a phone just to play games on, buy an iPhone. If you want a phone that's more than a toy, buy the Nokia E7.
