MSI's Wind was one of the many hardware lineups that intended to compete with the Eee line, both in notebook and desktop form. MSI faced issues in manufacturing as well as several delays in getting the notebook version out the door. It looks like the exact opposite might be true for the Wind desktop, which was not supposed to appear until at least September.
Apparently, though, the device has already been spotted in retail and is now appearing for sale. It's not the full version of the desktop - so don't get too excited - but rather the barebones version. It has been spotted on Newegg, with a limited number available, apparently, for only $139. Though the hardware itself isn't terribly impressive, it's still quite a decent chunk of hardware to get for that price. You'll still need to add your own storage, memory and other components. The full version of the Wind desktop is still expected sometime next month.
