i actually bought the PowerSleeve15 and it was too loose, I ended up sending it back, I got the PowerSleeve14 and love it. It's nice and tight. The 15 is too big. Get the 14. I'm actually going to sell mine, its only a week old, I need to get a laptop bag that can carry more equipment. But if your looking for a sleeve the PowerSleeve14 is the way to go for the PowerBook 15. Drop me an email if your interested in buying mine. I can give you a pretty good deal.
