The specs sound good, but I have not heard about the company and its product quality.
Let's wait and see.
With recent breakthrough of porting Mac OS X onto X86, my dream of having Mac OS X running on such small device will be very near.
Please note that current visualization software, like Parallels, allows installation of Windows XP and Vista, Linux on top of Mac OS X. By then, I have all popular OSes on one machine.
