Yet another vote for the Thinkpad X220. Made the move from a Macbook myself about six months ago. Tried out a long list of distributions and just about everything works out of the box if you're using a desktop environment like KDE. I'm now running Arch and Openbox which takes a bit of configuring but it makes for the quickest laptop I've ever owned. I won't deny OSX is a good, polished operating system but I can honestly say there's nothing I miss about it. I love the simplicity and the control Linux gives you over the system and I think Apple bury a lot of the nitty gritty but that's quite understandable really. Sure, there's been plenty of roadblocks along the way but I've enjoyed solving problems when they come up. More than anything, running Linux has provided a valuable learning experience.
