I read that electrical tape isn't safe enough. I'd rather err on the side of caution.
I like Macs, but there are many things I find frustrating with them. One of those things is that they don't seem to pick up wifi signals as well as PCs. Time and again I've gotten a weak or nonexistent signal, when PC laptop users in the room got a strong signal. I also hate that you have to buy everything almost exclusively from Apple, and how pricey they are. And never mind the fact that many things aren't compatible with the Mac OS, or aren't the same version as for Windows.
The main factor, though, is that I can't afford it. I got my Macbook in 2009 as a graduation gift of sorts from my high school. It was $999 at the time, and it was lovely and I was thrilled to have such a nice-looking, great-working (at least it seemed so), expensive laptop for free. But I can't put down $1k+ for a computer right now, and the "cheapest" Mac right now is like $1200 or something.
PCs scare me because of all the malware they are prone to. And Windows 8 sounds miserable, but I haven't tried it myself yet. But PCs are the most affordable, and you can get some decent basic ones for reasonable prices.
