Want to know the key differences between Apple’s iPad, Samsung’s Galaxy Tab and BlackBerry’s PlayBook? You do? Well, looky here then.

You won’t be able to buy a PlayBook until well into 2011, and by then Apple should have iPad 2 ready to roll. The second generation iPad may well address some of the apparent weaknesses in this company; we’d certainly expect more memory, a faster processor and a camera or two to appear in Apple’s 2011 tablet. And of course, Apple isn’t the only firm making tablets. The next few months are going to be very interesting indeed.
