If the Vaio UX had an officially supported linux distro (that made full use of all of hte hardware on it), I might have considered it. Same with the OQO (which has semi-official linux support, but not official enough to say whether or not it supports its EVDO modules).

Plus, those beasts are way too expensive. I guess I should have put that in my qualification: all of my LIST for under $600 ... not sure if/how-much more I'd pay for the also's I put after the list.
