Recently I was looking for a new laptop. The new MacBook Airs arguably have the best-designed hardware of any laptop on the market, but I object to certain hacker-unfriendly steps Apple has taken: namely, the use of pentalobular and triwing screws to make disassembly difficult. I cannot in good faith buy a computer from a company that so actively dissuades tinkering.

I've decided to go with the ThinkPad X220 instead. Although it's not quite as svelte as the Air, it is designed to be user serviceable. Hell, Lenovo publishes a manual with instructions on how to replace the system board (including details such as the torque each screw should be tightened to). And, although the X220 has a removable battery, its battery life is just as good as (if not better than) that of the Air.

(Oh, and the OS difference does not affect me because I will run Arch Linux either way.)
