I am considering replacing my PC laptop with a Powerbook G4. What I want to know is who owns one of the above and has switched (from PC to Mac/vice versa) and what was your experience? If I do decide to get a Mac, I am concerned about transferring my current files from my PC to the Mac. I.e. Word, Excel, and other common windows files; from my research it seem most Windows type programs will convert over. Thank you in advance!
