Query: If you have money to spend

Easy to use Linux with tons of tutorials, nice till you discover that you just installed the basics and to get more you need to open your wallet. Better off with a fancy LInux like Suse 9.3 or Mandriva or if money matters something like Ubuntu or Kubuntu or even Federa Core is you are not too much on the Internet. Their click and run technology is a good idea, except that most software they propose can already be downloaded for free from the Internet.
