So I just bought the new 2.0 Alu Macbook. This is my first MAC and my first laptop. The only thing I have a question about is; I heard that it is better to keep the notebook plugged in for as much as you can, and not to bother turning it off. just closing the lid and letting it sleep? what is everyone's opinion on this!? Also, for anyone else who has bought a new 2.0 What type of battery life are you getting, how many hours? I am pretty paranoid about this! And don't know if what I am getting is normal. Which is about 4-4.5 hours. Thanks for your help!
