As others have noted, the battery doesn't support all that's running on the phone for long (recharge 2-4 times a day). This is my first smart phone, but I learned most capabilities (so far) by experimenting. I read in the manual for some of the less obvious (to me) features (shortcuts mostly). I also had a problem downloading too many apps , especially the ones that start services (sucking up CPU time), and filled up the 1GB main memory before I moved them to the SD card. At first I wanted the physical keyboard, but I've gotten used to the virtual keyboard (vibration feedback (for key presses) does wonders eliminating the need for physical motion of the keys). Now I wish I'd bought a phone without a physical keyboard so I could use a shock-absorbent frame (not sold for this phone because of the slide-out keyboard). All-in-all, it's a good phone, if you can recharge it multiple times a day.
