You have to use your brain. Best of luck.
I'm pretty sure it can be done, because I'm doing it right now. And I don't possess the encyclopedic inventory of Linux skills assumed necessary to get any basic functionality from a Linux system.
You do need to learn for to use Google. I guess you need to be able to read too. And then you have to be able to reason a little. And type a bit too.
But back to the point of the article, I think it's a great point they're making. I'm only using Linux now because I got sick paying for Windows. I don't think Linux (Fedora in my case) is the greatest OS ever, but then neither is Windows. It has more potential to improve over short periods of time. I've seen this in the year and a half I've been using it. Since I'm using a massively improved version compared to the one I started on (which worked well BTW) and I'm still using XP on my other system. I do have the luxury of two desktop computers, so I can keep one aside for games and the other for everything else. The functionality of the gaming system improves enormously because of this, and the other system improves by virtue of using a "better" OS.
And it's free.
