Overall my experience with SimplyMEPIS was pretty positive with a few things that I didn’t like.
It’s a fine – but slightly dated – choice for almost any Linux user. Newbies should not have a problem installing it or otherwise using it. And experienced Linux users might also enjoy giving it a shot on their desktops.
If you’re not in a pressing hurry then you might want to wait for the next release which will probably have KDE 4 included with it.
