I've used several brands over the years and I must say that it's true: Once you go Mac, you can't go back. Aside from being beautiful, they're really easy to use. Apple thought of the littlest things that make it so much nicer than other laptops. My favorites being:
1) It only takes a few seconds to boot
2) When you've saved wifi settings, it automatically connects you once you boot without you having to do anything more
3) The charger is magnetic i.e. if someone accidentally trips on it, it will pull out of the socket safely
4) The trackpad is extremely easy and fun to use
5) The screen is SO much nicer than my previous laptops
6) I love the feel of the keyboard!
