First and Final thing : Sony is the world leader in everything
I bought this cell after having a long thought, options available to me being Samsung X600, Motorola E365, Motorola C650 (all in the same price bracket) - I can never think of buying a Nokia cell phone, as its not to my liking. Finally I opted for Sony Ericsson T610. It cost me Rs. 10, 500 with bill and warranty.
What I liked about it :
Bluetooth (not available in any phone at this price)
IR (transfer really very simple between 2 IR devices)
Screen Size (total of 9 line display)
Excellent resolution
Picture Phonebook (can assign cam pics to phonebook entries)
Good looks
Personal rings (assigning ringtones to a caller)
Some Drawbacks :
Camera (not as good as in Samsung phones)
2MB Memory (less as compared to samsung X600 - 9MB)
All in all a good phone.
