So like many others, I've been a pc user all my life and have been thinking about trying a mac once the mbp line got refreshed. I'm currently using a dell vostro 1500 which I'm fine with, but I'd like something a lot lighter and I want to switch to a 13" screen. I'm now looking at the new mbp 13 but I did have some questions I was hoping to get answered before committing to the purchase. How hot do MBP's get? I know the aluminum unibody looks 100x nicer than my plastic dell, but even when im using my dell on my lap without a laptop cooler, the dual core's stay around 55 degrees while websurfing and jump to maybe 65 degrees if I'm playing WoW or L4d2 (my dedicated gfx card stays around 5degrees hotter than my cores at all times). How "safe" is a mac? I consider myself a fairly intelligent pc user, I don't use any anti virus software and I try my best to make sure a link is safe before I download. The ONLY times I need to reformat my computer are when I'm streaming tv shows through random internet sites and accidentally click on some malicious ad (yeah I know its risky, but sites filled with ads are also the ones that have the most links for free streams most of the time). Will I have this same problem on a mac and OSX? Thx for the replies!
