Well I came from a line of Sony Ericsson Phones so this was a leap at trying something new. I have had the phone now for over 2 weeks which I feel is long enough to make a judgement on it. First and foremost the size of the phone is great. Slim, sleek, slender and light are just a few ways to describe it physically. The rubber backing feels cool as well. The button layout is easly functional and to navigate. I like that the memory slot is in the inside since it makes it more sleek. I have 1GB card in the phone and it picked it up no problem. I really like the OS interface - its not complicated to navigate through and looks cool as well. At first there is a slight learning curve as to were everything is located but once you play with it its easy - plus with the shortcuts you can get to what you want fairly easy. The speakerphone at times can be hard to understand but over all it works well. Music throught the phone sounds good to. Not bad for one speaker. It has at times closed out applications for no reason but I usually just chuck that off to Windows. The overall performance isn't that bad. It does slow down at times but not drastically. Overall, I am impressed with the phone and would recommend it. It has alot of features as well to boot. Worth buying.
