After going through several pc laptops I decided to make the switch to mac. While I'm really not in love with the operating system as of now, hopefully I'll grow to love it. The point is, Mac's are expensive and I want to protect my investment. So the question is, what accessories do I need? They seem to sell all sorts of things. I ordered the Rearth keyboard cover because while I know you shouldn't eat in front of a computer, but when it's 2 am and you have a paper due the next day, there isn't always time to stop for a snack. Is this a good one? Also, what will offer more protection, a case or a sleeve? can a put a case in the sleeve or is that just over kill. My laptop will coming with me to all my classes so it will probably get knocked around a bit. I try to be carefull but stuff happens. What combination will get me the best protection? I also see things to stick on like screen protectors and palmrest guards or whatever. Are these things really necessary? I mean, I know they're not necessary but how much would they really help protect the laptop? Also, what other accessories would it be could to have?
