I've seen a couple of you blast Android as not being a true replacement for Windows.... well how?
Can it run anything web related that Windows can? Yes.
Can it run Microsoft Office (obvious premier document control) as well as Google Docs to give you anything related to business/school typical use? Yes.
While it doesn't offer the exact same game library, with onLive and Google Play Store and the known expansion of gaming coming end of this year beginning of next.. well gaming options shouldn't be an issue either.
So, aside from specific things like programming or CAD software etc... for the greater majority of the mass populace, Android (or iOS for that matter) will be just fine as a tablet/laptop in replacement of Windows.
EDIT: and in the case of programming or other software... since Android is Linux based kernals, very soon you can have dual OS support with a full Linux build running.
