Where's the innovation? Why is an exciting new desktop just another imitation? Where does this obsession with innovation comes from? I will choose the thing that just works without getting into way over the innovation for the sake of innovation anytime. I'd argue, that there is little left to innovate within desktop, there is only room for relatively small improvements — and that's natural course of thing in maturing media. Take paper books: there was almost no innovation for hundreds of years: I say that's because their current form is optimal within constrains imposed by media. With computers we have less mature media and different set of constrains, but eventually it will settle down and the only innovation will be possible outside the desktop, like some next big thing that will replace it.
