Windows Phone Thoughts: Q1 2003 Laptop - Banias Anyone?

I'm looking at getting a new laptop in the spring (sometime around February) and I'm looking at a Toshiba Satellite 5200 series laptop (or perhaps a Tecra 9100). I'm considering waiting for a laptop using the forthcoming Banias processor - this processor is rumoured to be coming from Intel in Q1 2003 and will incorporate some pretty radical low-power technology (and a fat 1 MB cache). Any CPU experts out there know more? I'm curious to know what you think of it. I'm a little hesitant to put too much stock in the power-saving ability of a new CPU considering how heavily Intel discounted the power-savings of the Crusoe processor when it first came out. Screens consume most of the power on a laptop, but perhaps the Banias will be different. Opinions anyone?
