Actually, performance wise the Sony has yet to be beaten.

The A110 on the HTC Shift, the Samsung Q1, and the Fujitsu is infinitely slower.

The processor on the OQO Model 02 may have a higher "Ghz" number but it's also a lot slower then the UX.

Combine that with one of the SSDs on the UX390 or 490 models and you have a lightening fast UMPC with easily notebook PC capability.
