Pros: -Keeps my head toasty.
-Stylish
-Comfy
-Protects against snowballs

Cons: -Doesn't protect against snowballs thrown directly at the face. :/
-I didn't get 2 of them by accident.

Other Thoughts: Newegg is awesomesauce.

Pros: -Fits well in my Asus U20A. (not perfectly.)
-Works as advertised in both Windows 7 and Ubuntu without driver CD.
-Doesn't stick out nearly as much as most express card accessories do which is very nice.

Cons: -Sticks out about 1mm from the side of my Asus laptop.
-You need to connect the eSata cable BEFORE putting the card in my laptop, otherwise it just clicks and pops out with the pressure. (Perhaps my cable is just a little ill fitting?)
These two things are the reason for the lack of 5 eggs.

Other Thoughts: I would like to find an eSATA device that doesn't require a power cord or USB connection. I hate having multiple cables running just for an external hard drive enclosure!

This is a good upgrade for a laptop if you plan on using external hard drives and your computer doesn't have an eSATA port.
