I recently bought a new netbook and did not want to have it sloshing around in one of my existing full size laptop backbacks or briefcases. Shopping around, I found several small cases or sleeves, but this one seemed like the most quality solution.
This sleeve is very well constructed. In addition to its primary full size pocket, there is an easy to access one quarter sized accessory pocket. Both pockets are secured with continuous spiral zippers with fairly soft rubber zipper tabs (which are less likely to scratch anything). There is an attractive half star burst Case Logic logo on the front, and a three color Case Logic tab on the side of the sleeve. The foam and liner material seem to be quite firm and have good resilience.
This sleeve provides a very good amount of protection for its contents.
The accessory pocket is perfect for carrying a mouse and thumb drive. It is a bit too small to carry my AC charger and cord (but with 5+ hours of battery life, I don't need to always carry them).
Since the packaging says it is for 7 to 10 inch Ultra Portable PCs, I was a bit worried that my 10.2 inch Samsung NC10 would be just a bit too large, but it fits perfectly. I subsequently found information on the web that it will accommodate a computer up to 10.5 x 7.5 x 1.5 inches.
It weights slightly more that half a pound, and is amazingly guaranteed for 25 years!
I am very happy with my Case Logic Neoprene Netbook Sleeve.
