I bought the model just a week back. And within such a short time span I came to know that the SE T100 is indeed a nice phone and has good look. It is very sleek and lightweight. Battery performance is also fine. Its having a very good text language T9.
But there are some major changes SE T100 needs to make. Its options are not as user friendly as Nokia, and again the main problem is with Phone Book. You cant view the number and the name simaltaneously. Both, number and name disappers after some times one by one. Again the problem is with LED. Actually it is used for finding network coverage. Which can also be viewd on display itself. But the LED is always glowing .. glowing.. and glowing... You are not able to turn off.
But overall the model is tooo... much good.
