The best laid schemes o’ Mice an’ Men, Gang aft agley. (That’s Robert Burns, friends.)
Installing Linux is not as easy as it sounds. I installed SuSE multiple times last night. Once it actually installed OK and booted to KDE. But it only booted once and after that I couldn’t boot to anything. So I ran FIXMBR and could then boot to XP, but not to Linux. So I decided to start over again. But I never could get back to that point.
This is the reason why Linux is not on more desktops. When it’s as easy to install and use as Windows then it will spread beyond the enthusiast market.
