If computer is your hobby, you will, sooner or later, run into Linux. Cos only Linux (not Mac, Windows or any other OS) gives you that power to tweak/tinker, virtually every bit and piece of the OS. That's why there are so many distributions, so many forks, spins, respins, and multitude of application software for a single task. No surprise, many hobbyists come, wander in the linux world, but a few really stick to it, rest go. Cos? Not all the distributions are polished, stable, easy and powerful. Most often sticking to linux depends on hitting a good no-nonsense distribution (like PCLinuxOS, Mint or Mepis) at the first chance. IMO, PCLinuxOS tops the list of distros that care for new-converts.
