No regrets here. Awesome machine. This is my second Rev A laptop from apple. My 1st was a G4 powerbook, then my new macbook. Zero problems with either one. I love the size for portability. Bottom line is.. is the macbook you have now doing everything you need it to? Is it to slow for you? If your happy with it and working the way you want, keep it. Wait 1 year and grab the next generation which will be intel i7. That processor will smoke anything out now.
