I hate Macs for one reason. Their price.
on the OS side, its really up to user preference. I never had problems on my W7 and certainly no viruses in the last 10 years.
Macs and Apple

i have 5 brand of laptops in my household
asus, gateway, hp, apple, samsung
the mac book pro is the only one that died and it costs so much to get a new mobo. it was out of warranty but it wasnt the oldest out of the bunch.
hence again my hate for it comes because of the price.
(its my bros mac)
