I work on two laptops, depending on the project: a MacBook Pro, and an X-series ThinkPad. Both are great. Granted, I'd be on the MBP all the time if it weren't for historical reasons, but I have no complaints at all about the ThinkPad. If you don't want to use a Mac, it's the best alternative I know of. I had to use someone else's VAIO for a few hours recently, and it sucked. The keyboard is lousy, and has a horrible layout if you're used to Fn and Ctrl keys in the places where Apple and IBM (Lenovo) put them (and you don't properly swap Caps Lock and Ctrl). I ended up plugging in an external keyboard to be able to get anything done. In addition, the whole thing looked and felt gimmicky.
