All of the backwards-looking nostalgia from all of the commenters posting so far are exactly why Apple were able to get out of the door with iPad first and slowly destroy Microsoft's pre-eminence.
Had Redmond produced the iPad, it's users would have rejected it - and demanded a "Start" button! Quite ludicrous. Ballmer may be gutting the company of all of it's talent and slowly running it into the ground but, unbelievably, I am with him on this one.
