Tried to put Linux (Puppy Linux) on a computer, and it was very difficult to get it to work. Actually, it didn't fully work.
When they make a free operating system that installs easily and then functions easily--and, as freepers on one of the EU court decision threads stated, when more software comes out that works on Linux--then there could be a flood of people to move to Linux (it is free, after all).
Why should Linux install easier than Windows? In fact I could argue that, since it's a one-time event, the install should be irrelevant.
Once installed, though, I have found that Linux is usually easier to run and operate than Windows.
But that's just my $0.02. :)
Funny thing is that I know Linux fairly well (I run Gentoo on my laptop and on my home server, an old white box), but I couldn't get Puppy to install, either. You would almost certainly find that openSUSE (which I highly recommend) or K/Ubuntu is much easier to install.
