Given time I'd wager that tablets will be just as ubiquitous as laptops, and that the technology itself will become cheap to the point of almost disposability. Tablets are the next level of media consumption and fill the void left by laptops for tasks such as ebook/text reading that more traditional form factors can't fulfil. I don't have to worry about printing off every article we're sent to discuss in our seminars at university anymore because I can just load up the email and open the file at any point during the session, and once textbooks are more widely available through digital stores it'll almost be as big a no-brainer to have a tablet for university as it is to have a laptop. In your specific case I'd definitely take a good look at the HP Touchslate first and compare it to whatever Apple comes out with. WebOS is the closest thing you'll get to the feeling of iOS and is in many ways a better platform, minus the obvious shortages of Apps and accessories ecosystem.
