Well my point about the huge canvas would be that you could scale it down for logos and stuff like that. But meh, to each his own
using a .PSD or Jpeg or .PDF the file cant be scaled more than 200% before you can start seeing the pixels and Jpeg artifacts.
so for the hot sauce company making a billboard they would have to get the logo you did for them and have it recreated in Illustrator.
I'm saying this because I think if you tried illustrator you would love it, and I think you you could do some killer sh*t
