Very few people will switch to Linux because Windows 8 is a mess.
Correct. But some will, and the availability of mainstream games (obviously all of this is assuming Steam brings some games with it) will make it more attractive. At least for me. And I have a hard time believing there aren't others. That's all I was trying to say.
Actually secure boot doesn't make it any harder to create a linux distro, it just makes it slightly harder to install one (because you have to disable it before you can do so unless your distro and hardware of choice have the right keys).
With secure boot enabled by default on most/all new desktops, distros will either need to have you disable it (difficult for novices, and some may be reluctant to do it), or have the appropriate software and keys. I'm not saying it's a huge thing, but I do think it makes viable mainstream distros slightly harder to produce. If not, why the uproar about the change?
Seriously, I've been reading Slashdot for a little while, and the latest run of articles has been mind-twistingly sub-par.
