Apple have the happy knack of making difficult things appear reall simple, something PC manufacturers - quite possibly due to Microsoft - struggle with.
A good example is DTP, Pagemaker and Indesign are ideal on Apple, but frustrating on PC.
Same goes with iPod, iPhone and now iPad, nothing new, but really well packaged for humans.
Having said that, Blackberry has the business market sewn up, admit work blackberry craps all over personal iPhone for business, but give me a iPhone for when it is my time, I think the same will go for 'BlackPad' when it is released, it will have business users, iPad will have after hours users.
