How strange that my system software is so big. I installed iLife '05 -- is that very big? Other than that the only things I have added are about 20 songs and 500 MB of photos. Oh, and Cocktail and Contribute. Jeepers! It's prolly very good I am switching this computer -- no idea what might be going on that's taking up all that space. Thanks for your help. Will advise re return process.
