Ok so I have a 3 year-old MB thats starting to have problems. The biggest one seems to be that sometimes it doesn't recognize the hard drive while booting up. I found that if I turn it off again and give it a shake (which btw just doesn't feel right) it works. I'm beginning to feel a little nervous as I rely heavily on my MB as a student. I also would like a considerable speed upgrade because the mac is starting to feel slugish. I think I have three options: 1) Buy a netbook and install OS X on it and use it as a backup (Maybe something like this: http://bit.ly/HackintoshNetbook) 2) Buy a new MB or MBP ( This seems highly unlikely because I'm tight pressed for money) 3) Try to upgrade my current MB (Maybe a new SSD, more RAM, ect. ect.) (This thread gave me that idea http://bit.ly/5TwIaV) What should I do?
