Close, but I won't be buying...
I like the screen, and I'd probably be able to live with that irritating keyboard nubbin mouse, but there are some other issues.
Lack of an Ethernet port is no good really. Sony should have called this thing the Vaio Air. The fact is that I probably won't have an 802.11N network for a while, and even when I do, it won't be nearly as fast as the gigabit port on my HP2133 (or probably even as fast as the piddly Via cpu bottleneck will allow an nfs copy to go.) They'll probably supply ethernet via a docking station that goes in that proprietary port.
Mostly, though, I just seriously doubt that Linux will work on this device at all. Sony has historically done things in as proprietary and bizzare a way as possible, so you more or less have to run Windows and use all the Sony software. Who knows if you'd even be able to run XP.
So I guess I'll just wait for that HP2140, since it's so cheap I can justify replacing my 2133 after a year... especially if I can get the damned video drivers to work properly.
