The only advantage Motorola Droid has over SE Xperia X10 is the QWERTY keyboard. Otherwise X10 is simply better in every aspect - battery, camera, video recording, processor, internal memory etc. But it will cost a bomb when released.
Anyways, you'll have to wait till X10 is actually revealed. SE is well set up in India, so if I would have been you, I would have been more inclined towards SE.
Wait for MWC in feb and see all the new devices & then take a decision .. Cos since ur planning to spend more than 25k on a phone its better to wait and then take a wise decision ..
Fones which are revealed in MWC generally take more 8-10 months to get realeased. He can't just keep on waiting.
