As a "switcher", a 3 year owner of a 17" PowerBook, and the owner of a Cube, I can understand your comments and your feelings. However, my office purchased a ThinkPad X32 for me at my request 6 months ago, and it has been a wonderful piece of equipment. It's everything that my wife's iBook (and the 12" PowerBook) should have been. Small, 2.6 lbs of weight, removable optical drive (in a docking base), and up to 8 hours of battery life with the optional battery (5 hours on the standard battery). It may not be pretty, but it works. I don't have a huge issue with fingerprints on this model either.
If Apple would build a powerbook with this feature set, they would have a purchase from me. This X32 makes the current 12" iBook and Powerbooks look like a brick in comparison. That being said, I still prefer the PowerBook for day to day use because of it's screen, and because of OS X.
