$600 will buy you a 1.2GHz C7-M, a 120GB drive, 1GB of RAM and Vista Home Basic, while $749 bumps you up to 1.6GHz and Vista Business and adds Bluetooth, another gig of RAM, and a bigger battery. There's also a mysterious $849 Vista Basic model listed as having "regional" availability (the others are listed as "Smart Buy") with Bluetooth and bigger battery, but we don't see why it's more expensive than the Vista Business version. Regardless, what really caught our eye was the $549 model that shares the same specs as the $600 unit, but looks to be running SuSE Enterprise -- another rumor that's come true.
The 2133 should be available on April 7th.
