If by pushing away the windows metaphor we have to lose multitasking (no, the iPad does not provide any multitasking capacity), well, let the windows be welcome…

If by pushing away the keyboard you mean that the virtual keyboard will be enough, well, I think about all the developers laughing off loud in this moment…

The folders are not an “oh-so-old” metaphor – it represents a mirror of the way we operate daily in our offices and the most immediate mean of categorization that pops into my mind. Content tagging is an alternative but in many cases does not represent a solution (ever thought about zipping a folder and send it to a customer?)

The mouse? Yes, perhaps the only expendable item in the list.

And I still believe that for $829 one can purchase a high-end netbook and get more features and better value for money.
