but PC simply means "personal computer", if you connect a keyboard and a mouse to an iPad then surely it becomed a "personal computer"?
it certainly can't be called a "tablet" any more if you using it on a desk in a mode that could be described a "laptop-like".
in fact, when was the last time used the "post PC era" marketing nonsense? have they realised it was mostly bollocks and dropped it like they do with most of the nonsense they come up with?
