So they're finally making Macs for Intel processors? Apple was making builds of their OS X platform for Intel processors for years in case Power PC went in the tank. I've never liked Apple's notebooks--they're made with too much flimsy plastic and the keyboard is terribly unresponsive. Plus, I've had enough problems with my iPod to trust their quality control.
Anyway, Thinkpads are the best designed notebooks out there. Their keyboards alone are worth it (better than any I've ever used, desktop or notebook). Plus, IBM (or Lenovo which bought out IBM's Thinkpad business) makes Thinkpads with Intel Centrino Dual Core processors, which is basically the same cpu in the Intel-Macs, so I guess you could soon have the best of both worlds--OS X Tiger running on a Thinkpad!
