I just just picked up the previous generation MBP 15.4" and now am looking for a case. I would like something thin and light like a sleeve, but I also need some space to carry the power brick and a mouse. These are the ones that I have found so far... Acme Made The Slim Cargo - $129-$249 Brenthaven MetroLite II Black - $79.95 Booq Boa Slimcase M90 - $115 Waterfield HardCase - $239 Does anyone have any experience with any of these or have a recommendation for something else that suits the bill? My only other concern is that I want it to be able to fit the new MBP as well. I would hate having to buy another case down the line since some of these cases can be quite expensive.
