Why do we (currently have) 277 questions tagged with tablet? This seems like one of the most generic and pointless tags out there.
I realise that back when tablets were new and unusual in the Android world there was even a competition with prizes for questions tagged as tablet but tablets were so rare then that this was understandable, not so any more, these days it would just cause us problems.
Go through a tag cleanup exercise to pare down to just questions that really are specific problems that would only affect tablets but aren't specific enough to need tagging with the model (I'm struggling to think what they would be). Edit the wiki to note that the Tablet tag should only be used when really needed.
Leave things as they are, tablets really are a different category of questions that need identifying.
