Exodus to mobile devices like tablets and smart phones. It's no secret the PC industry is losing customers as your average non-techie is able to do almost everything they want on a tablet instead of some beige box in the corner of a downstairs den.
I get this kind of blank stare from colleagues at the office too. Let's face it, yes there are many things PC's can do that tablets don't, but those things are being done less and less by the average device buyer. Us techno-literates are a minority. It's myopic to think that just because we need PC's, everyone else does too.
Sorry, I know this wasn't the debate your comment was necessarily aimed at, but it's relevant..
