Oh, it's not hard to find which model is certified. It's hard to actually find it selling in a store!
Also, I don't want to buy a ThinkPad if I have to buy it with Windows then wipe that.
So my choices are laptops that come with FreeDOS or Linux and that are actually certified for Linux. Because, rumor has it, even some laptops that do come with Linux don't have proper Linux support for all their components -- they are built with the assumption of a Windows install.
At this point you don't have that many choices and if you also want a particular hardware configuration (say, i5) the choice narrows down a lot.
