The ironic ending of the blog post is interesting. He's running Ubuntu... on a MacBook Pro. Even if you hate the software and all things iOS, it's hard to find a better designed laptop.
So, in my effort to stay true to my Unix'ish roots, I've gotten a Motorola Lapdock real cheap, its at least as comfy as a macbook Air, and I'm plugging in things like .. raspberryPi, MK802/808 Android or Ubuntu sticks, my desktop 'slab PC', and so on. I think I'm close to kicking the habit - they /really/ lost me at the drop of the MacbookPro17" .. my existing one will run into the ground, and I will soon put Linux on it.
In the meantime, I would suggest that those looking for an alternative to the sexy nature of the hardware aspect, albeit with a little extra effort, switching to Ubuntu-on-a-Stick is really a pleasant treat.
