I am in the market for a sleeve for my new macbook air. I have been doing some searching and I think I have narrowed it down to either the Waterfield Travel Express or the Timbuk2 Escape. I am bascially looking for a sleeve style case that has room for the power adapter and maybe a slim mouse. It will mostly be in my backpack but would like it modular for when I want to take it out and use my backpack for other stuff. I was also hoping for a vertical version but haven't seen any yet that also are slim and have room for the power adapter. If any body has any suggestions on either of these or knows of a different case that is vertical please let me know. thanks.
