Really almost all of us here don't just use pro-tools. Almost all of us use pro-tools in combination with something like Sound Forge or Wavelab. I use Wavelab for my basic needs and when I want to make mp3s I also use it so that I can make use of my DirectX pluggins such as Auto Tune. If you are trying to decide on the type of system to use, just remember that pro-tools probably won't be your only program, however pro-tools is one of the most powerfull and versatile programs out there.
