I had this phone for 2 years ( 2010-2012) before moving onto the Orange San Francisco, then the Samsung Galaxy S2. I really love the Nokia E63 and I will never sell it as its such a great phone. Its based on the Nokia E71 which in its day was better than the current Blackberry.
The battery on the E63 seems to last forever, easily well over 1 day of the heaviest use, and I was laughed when I saw my Iphone having friends bringing their chargers into work as their batteries would literally die after a couple of hours.
The phone has no GPS but instead works by locking onto phone mast signals which trust me, is just as good as GPS. It finds your current location in 3 seconds, in contrast to my current Samsung Galaxy S2 which unbelievably takes 20 seconds.
The keyboard is great, the torch function is useful and handy, the camera is good, the internet works best by installing Opera Mini as a browser. This phone never let me down, it was always fast and responsive with a stellar battery life, so glad I chose this over a Blackberry. Many people actually mistook the phone for a Blackberry whenever I used it, so why pay more? Only downside and the reason I eventually moved up to a Samsung Galaxy S2, is the small screen but that's no different from other similar phones.
