Ubuntu (Linux) and other computer questions

Have you heard about it or what? At the same time what computer to prefer/use as well?

As for me have heard about it and tried it and also Novell Suse (Linux). Tell you the truth, found both of them aren't worth aren't in the long run. As what they claimed to be. Will go with Apple Mac then Ubuntu because I have found Macs are much easier to use. At the same time had it up to here with Microsoft Windows based computers because have had my problems with them. Even though I have found Windows is much easier to use Ubuntu or Suse, but still found all of them are hassles in the long run.
