The Microsoft Surface seems to be trying to take on both the iPad and the MacBook Air (with the Pro version). I have recently been looking into the Surface, probably not Pro but not necessarily, and would like to hear opinions from people who have used all the above devices, or just opinions from people who have tried it out. Is it an iPad killer or an Air killer? What do you think about Windows 8? I would love to hear all viewpoints and sides of this argument.
