I have mixed feelings: one one hand, new technology is almost always at least a little exciting, but on the other hand, I'm somewhat less enamored where pushing the envelope in mobile performance always makes "mobile performance" mutually exclusive-- that I don't think we've seen the breakthrough in graphics processors that we've seen in main processors, a la the Pentium M (do more with less) and its derivatives. Although, Nvidia being able to clock they're SPs asychronously, is a step in the right direction.
I guess hose thoughts bring up another question: Does it seem, that most of the market movement (corporate purchases excluded) are driving at the extremes of the spectrum: one end being the gaming / high-performance (like this Qosimo, the XPS, OCZs first offering) and the other end being the ultra portable / mobile appliance (Eee PC, WIND, U110, MacBook Air)?
