Not only who runs one distro at a time, but who runs one OS at a time?

FWIW, my order is:

CP/M, DOS 3.3, Win 3.1, 3.11, DOS 6, 6.2, Win 95, Slackware 3.6 (?), Redhat 6, Mandrake, Win 98, BeOS 4.5, Win 2k, SuSE 9.0 (?), Win XP SP3, MacOS X 10.4, Ubuntu, MacOS X 10.5, Jolicloud (or whatever it's called), MacOS X 10.6, MacOS X 10.7, MacOS X 10.8.

But I've never run a single OS or version of an OS exclusively.

So at the moment, I've got WinXP, Jolithing (on a netbook) and a mix of OS X 10.7 and 10.8. The best one ever was BeOS (at the time) and I'm planning to give Win 8 a go on a tablet (I don't like Android or iOS on iPad, although I have an iPhone), but not on the desktop.

Navigation By Cockney?

I honestly don't know why this isn't the default setting. I actually downloaded the Nook user manual just to see if it was possible to use the cover art (which they already have downloaded, for the CoverFlow-like browsing) as the screen saver, but, no.

I mean, how can I use my Nook to pick up chicks if I can't subtly cue them in to the fact that I'm reading Twilight?

I don't understand the comparison between this and a Mac Mini. Fair enough, they try to be small form factor computers, but the end is surely different. the Mac Mini is designed to be a small, neat, consumer electronics device. Essentially a computer that is as easy to use as a DVD player.

The Shuttle is designed to be an expandable PC that has lots of flexibilty and can be modified by changing components so that it can fit the user's needs.

If the Mini does everything you need, buy a Mini. If you need flexibilty or expandablility, buy the Shuttle.

Just because they both try to be small, it doesn't mean that they are necessarily comparable.

In my (admittedly fairly worthless) opinion, the summary was using Mac Mini as a comparison just to make the front page.
