Good, small, cheap: pick three!
It is small, it is light, got a classy the battery last for days, software is ergonomic. It takes microSD card so you have an MP3 player. It got bluetooth, great predictive text entry. Earphone jack is a regular 1/8". The calendar and todo list are usable. Tt's the cheaper phone I can get! 50$! Cons: No EDGE or 3G. Mostly useless USB connector (you can't charge your phone through USB, only transfer files and exchange data with Ovi suite, which you can do with bluethooth anyway. Love it.
