I guess a lot depends on your luck when it comes to mobile phones. I made the switch from Nokia to SE T610 last year. There are a couple of reasons why I made the choice.
Same as you, I am sick with Nokia’s innovation. Their creativity is nothing more than just changing the cover and shifting the buttons. I wanted something new, sleek and has BT. SE T610 fits the bill perfectly.
As a seasoned nokia user, you won’t get used to SE as the buttons are direct opposite of each other. I, however, got used to SE’s interface in abt 1 month. Not too bad, eh?
The pain now is the usage of the BT ear piece. It does not pick up the calls as fast as I had wished, and thus I ended cancelling a lot of calls when the intention is to pick up. :x Also, by the time it really pick up the call, the caller hit the busy tone…. there are simply too much frustrations for this SE T610. Some of my friends are equally frustrated with their T610 while some are very happy with it. I regret making the switch and is now waiting for Nokia 6230 to be launched.
If you ask me, I would say the reliability of the phone is the most important. I can get used to some lousy user interface, but I can’t accept a phone that cannot receives calls well.
