I am a MBP user, and use Illustrator for logos. What is your profession, what is the logo for? From you post, you don't sound to experienced, no offense. So you might want to post the logo you design and get some feed back from the designers. Typically for logos, you want to do many many concepts, around 30. And then pick the best ones from that, then do different concepts of that. Its tedious yes, but thats what makes a good logo / designer.
