For anyone still holding out, the new Intel Santa Rosa platform for notebooks is out. Most of the big notebook manufacturers have already released new computers with the new chip set. As I understand it, the main advantages are:
1. 800FSB - faster front side bus (v. 677 max before)
2. New processors - 1.8 - 2.4 GHz - with larger onboard cahces
3. Higher performance integrated graphics - the vista Aero interface should run fine on the new integrated graphics, which saves power over discrete graphics for longer battery life
4. Intel "turbo" memory - a Flash memory cache of the hard drive which allows for really fast access of common programs and extended battery life (this is optional)
5. Draft N wireless (optional)
Lenovo has a new T61 Thinkpad out with a 14.1" widescreen, which is exactly what I was interested in. With all the new features, it works out to be about $100 more than the z61t, which is what I was looking at before. I think people who haven't yet bought a new computer should definitely get the scoop on these new platforms before moving. At this small price difference, I believe the upgrade is a bargain.
