Motorola are still as bad as ever- awful, awful software- nightmare phones. That particular SE model is a peice of s... tbh. The samsung is great but it will break for no good reason...
Dont place too much emphasis on features like a camera and mp3 plyer at least not above Calls(quality/reception) texting and batterylife
A nokia is the best bet imo. The n80 is a stunner. It is 3G but unless your using that feature the battery life will be fine. A bit big but it packs a lot of features. Get it in black ooooh babeh
