I use a Lenovo T60 running Windows XP, with Ubuntu 6.10 running in a VMWare virtual machine. VMWare Workstation is really cheap and VMWare Player is free. You can find many preconfigured Linux virtual machines on VMWare's website. Power management and battery life in particular suck on Linux. Even if you can get it to actually work (lots of Googling + configuring) you will get at best 2/3 of the Windows battery life. Plus, I don't have a lot of faith in the quality of the suspend-to-disk functionality in any flavor of Linux.
