It's a no doubt great phone. But may not keep you satisfied if you are planning to keep it for a couple of years.
I like Sony and SE stuff in particular, but the W960 couldn't make a hit in the market anywhere in the world, despite the features it couldn't compete with others in market, especially the iPhone.
Phone is feature packed, but the OS might have made it loose a bit. I had been eyeing it many months before it actually launched, but lost interest in the way while learning all about it.
But nevertheless, it's still a great phone and a lot of features and applications are available for UIQ 3 platform.
Also, P1i is immediate reply for almost same thing with a lower price tag and of course minus the awesome Walkman player.
