Hi everyone, Just purchased a new macbook pro 13" 2.4 GHz yesterday. It is the most expensive thing I have bought for myself other than my car. I'm hoping for great performance and durability/reliability out of this machine! BTW, since this is so expensive, I'm ultra protective and paranoid with keeping it as clean and running efficiently for as long as possible. I had a few questions: 1). I bought the moshi keyboard cover and it is covering the keyboard fine, but should I take it off periodically to avoid the overheating issue? I understand that the keyboard has vents that might be blocked. How often do you guys take it off? 2). Is buying the moshi trackpad cover advisable? How about an actual case for the macbook pro? is it worth it? I have a zeroshock sleeve that I a using, but would a case provide extra durability in the event of the unit dropping. 3). I was wondering if I should get a screen protector? My three year old came in and made a few smudges on the screen this morning...any tips on how I should clean those smudges. Also, what should I clean the actual keyboard and palm area with? Any cleaners or would a kleenex tissue paper work fine? 4). Should I keep the unit plugged in all the time when I don't need to be mobile and I am just using it while sitting on my desk. I know it has a lot of battery hours, but I don't want to use the battery power unecessarily. At the same time, I also don't want to have a high power bill or harm the computer by constantly using the AC adaptor. 5). Lastly, would getting Apple Care be a good investment? Can I also get a loaner in the event that something goes wrong? Sorry for those long questions...I don't know much about computers much less macs, but it looks like I have come to the right place! Thanks!
