I just bought a 13' MacBook, and I love it! I'm interested in getting a cover or sleeve for it, as I don't want it to get scratched etc. I've done some reading here and there about them, and have seen that some of the hard/snap on ones can actually end up scratching it anyway! It doesn't have to be a hard case...that's part of what I'm trying to decide on. I'm ok with "color" too. Also, I want a mouse for my MacBook. Some tasks it's just easier! Any advice on this? I believe I understand that any mouse that plugs into the USB will work on it, so would you advise picking up any ol' mouse or buy specifically from Mac store? Thanks!
