30 years on a pc for me, I bought a 13" i7 256g air, love it, best mobile all around computer I have ever owned! I'm hooked, I ordered the 27" thunderbolt display, bought the 3tb time capsule, mouse, keyboard, trackpad, apple external dvd drive, g-tech external small 750g drive, about $5k in software and apps etc. It's like a crack addiction for nerds, am I the norm? Ohh yea, I have never owned an iPhone so I'm going to buy the iPhone 5 now... This all started because I bought the first gen iPad. LOL It's been expensive so far but I have to say worth every penny!
