Fake Steve does an analysis of Why Dell will not bounce back. Funny, self indulgent piece, but loaded with the ring of truth. From FSJ:

Bottom line is this: the only innovations worth making are the ones involving product ideas and product design. I mean, Duh. Right? It’s pretty obvious. What’s amazing to me is how few companies actually seem to realize it. To sustain an edge in any market you must make better products than your competitors, consistently, over and over and over again. Just making the same products as everyone else but taking a little friction out of the system can give you an advantage, but only a temporary one.
