I’m planning to pre-order Surface but am just unsure if I can use it for any good purpose?
Yeps the Pro version with the Intel processor should be able to manage it, however need a hand-on on Microsoft Surface Tablet first to be more specific with my answer. :P Eagerly awaiting the October 26th. launch of the RT version, Pro will follow later, probably in January next year.
The Pro Surface will be having specs comparing to Ultrabooks with i5 processor. :)
It should work with the x86 (Pro) version of the Surface and be able to handle it. Just don't expect the same performance as an A/V workstation.
