I really appreaciate my iPad and I use it daily for a limited but valuable scope of use.
That said,even with the limited demands I place on it, it locks up, applications crash and it requires updates - Application updates are almost monthly if not more frequent. I demand much more out of my windows laptop than my ipad and I honestly can't recall the last time it crashed. Admittedly I have a Mac at home for my kids and I recently bought one for my parents because I think it is an excellent platform for a particular type of user and I enjoy using them as well. But rooms full of slow, virus laden Windows PCs with smoke rising out them is more the stuff of myth and agenda than reality. I look at the Windows facet of Surface as its primary selling point.
