I was a long time Windows-only user. I hated Mac OS with a passion, but then after multiple laptops dying so quickly I jumped to a late-2006 Black MacBook. I've never looked back since. That laptop will turn five in January, and it's still running!
Then of course my girlfriend has two MacBooks - a White personal one, and a MacBook Air for work. Once we move her company will be sending her an iMac. So yes, five Macs in one house.
Then there are the multiple iPods and iPhones and planned iPads...
Seeing as I couldn't afford a Mac Pro, but didn't want to go the Windows route, Apple has continued to make money off of me through my Hack. There's no way they can knock it!
