This handset was the one on offer everywhere at Xmas 2009 with different details from different stores - I got mine from a different provider. The battery is slightly more powerful than that of the model below it, the E1100, though both models share the same simple yet colourful interface that shows time day and date by default without having to dive into deeper menus. This battery's rating of 540hrs' standby is an exaggeration as the E1100's lasted exactly 120hrs for 50Mah less power rating, but knowing this one will last up to almost a sixth straight day of being left on, is useful. The only time the battery life is much lower, is if the autolock turns off in your pocket and the torch is engaged from the Applications menu - then that will kill the battery very quickly.
However, that one flaw - which happens more often when trying to carry two handsets in the same pocket - is the sole disadvantage to this cheap and cheerful "anti-iPhone" - no camera and no music, just a phone for calls only. It's best used as a cheap/spare/emergency PAYG handset that you will leave to sit around for a year until it falls off its own network - then you can put whatever SIM you like into it and use accordingly. It's also cheap enough to finally find out whether Virgin Mobile SIMs can fit in T-Mobile phones considering they share the same network. In fact, that's the reason I'll be buying one myself.
