Once a Mac, one never look back. I started using a Mac 5 years ago and since then have upgraded three times to newer Macs. Started with the PowerBook G4 to my current MacBook Pro, 27 inch iMac at home, 2 iPhones (one is 1st generation and the other 3GS), iPod classic and of course the iPad. It's quick, intuitive, doesn't crash, does not hog memory and last but definitely not least. . . . . . it does not run on Microsoft.
