Honestly, I knew this was going to be a Mac thread based on the title.
I've had my MacBook for 2 years now. I use a PC at work, so I have nothing agains them. The only thing I can say is that my Macbook (standard, not Pro) has never, ever, crashed. Now I know that anyone in the PC crowd can tell me the same thing, but I owned two PC laptops before that, and they crashed regularly. To me, when you have important data on the machine, regularly = 2-3 times a year. My MacBook is overpriced. But I haven't installed a single piece of protection software on it and have never even had a slowdown. THAT SAID, I don't buy games. The only thing I do is web, work email through VPN, home email, and Open Office spreadsheets, word docs, and database.
