Pros: Good price, easy to install. Seems to do the job.

Cons: Instructions are non-existent, but if you're doing this yourself, you should probably have some sort of clue.

Overall Review: Macbook only had 1GB when I bought it. Bumped it up to 4GB and what a difference. I think at the time I bought this, Apple wanted about 700 dollars to include 4GB. Good service from Newegg. Order shipped out same day, and free shipping was nice.

Pros: Compact, nice design, easy to stash in a backpack along with books.

Cons: Runs a bit warm after a while.

Overall Review: Bought this for $349 last week. Had a shipping problem, but after a little coaxing, Newegg took care of it. If you're a student like I am, this is a great little machine to take along for the day. It weighs about 2 pounds, and seems to get about 4 hours out of the battery.
