I remember Steve Jobs saying "good artists copy, great artists steal". Apple has been known to steal ideas from competitors by taking the idea and implementing in such a way that it looks like they had invented the idea in the first place or at least have the best implementation of the idea. MSFT tend to just copy an idea and implement it rather poorly that looks like a really cheap imitation.
I hope Apple steals the Microsoft Surface idea but rather than having it just as a "table", the big ass tablet could be placed on a wall, flat desk or at an incline and I hope that they include a usable UI that makes sense for the form factor and the multi-touch interface like they did with Cocoa touch for the iPhone/iPod Touch. It seems to me that MSFT's surface is just an overpriced tech demo with no dedicated API or GUI that third party developers can leverage to give an appropriate and consistent look and feel.
