It's pretty clear that this is not a problem with the Windows Mobile Operating System as it is pretty smoothly running on the new HTC units and also on several other models. Few weeks back Sony Ericsson announced the new XPERIA X1 ... I think this is the first Windows mobile device from Sony Ericsson. Actually I was expecting a Windows Mobile device from SE for a long time. Because all the SE phones I have used have been extremely good. T610, K700i are among them.

XPERIA X1 looks and sounds like a very promising device as the configurations are above the current available devices, this applies for the screen resolution, processor, memory and most importantly the battery life.

Anyways still haven't decided about buying this. may be I will :)
