I have to admit, as far as -hardware- goes, I like the Xperia much more than the Touch pro. The TP has TF3D which is way better than the panels interface on the X1, as one big example... and if I remember correctly, the X1 doesn't have the same qualcomm chipset that causes the poor video performance for the TP.

Still, I cast my vote for the touch pro based on availability, and the doftware that runs on the phone. The xperia could have been a hell of a seller, I think. I pretty much settled on the touch pro due to lack of alternatives (but that doesn't mean I don't enjoy my touch pro).
