I have used many different types of computers/OSs over the years: 

Mac 1989-2007, Windows (DOS) 1988-2007, Quantel 1990-1999, SGI (Softwindows and UNIX) 1993-1998, Abacus 1997-1999, Chyron 1993-1997, Pinnacle 1997-1999, Infiniti  1998-1999, etc.

... but Mac is "home." It's what I prefer because it is a superior product. I have 5 Macs in my home, and my first Mac, from 1993, still runs too.  I have never needed to take a Mac in for service. I can pop in new memory cards, processors, and power supplies for myself. I've never had a virus, and I can run Disk Warrior on external drives to fix them for myself too.

I am very happy with what Apple has done in the last few years, -- iPods, iTunes, affordable MacMini, AppleTV, iPhone, switching to intel chips, BootCamp...  imho, Steve Jobs is a brillant visionary. Coolest CEO ever, imho. ^^
