Having been using Mac for about three years now, I cannot imagine myself going back to a PC anymore. Every time I'm forced to use a PC, whether it is in school or maybe borrowing a friend's laptop, I can't help by being frustrated or even start screaming to whoever that might listen, "can you please speed up my pc?" But of course no one hears and I'm forced to wait until the window or browser that I need pops up.
I know I know PC is geared more towards professional users like gamers or software people.. but how do you bear all the viruses and constant lag? My Mac never gives me that problem. But who knows though now that Steve Jobs is not around anymore..
