So I've been in the market looking for a perfect fitting bag(preferably messenger!) for my macbook air 13" that compliments it's light form and size. Since I usually only carry the mba to my office with my kindle/book and newspaper there's not really a need for much pockets. The only requirement is for it to be slim and lightweight. Below are some of the possible ones i found. However I'm still undecided and looking for recommendations!

Also if you have come across similar slim-formed bags or other recommendations for the MBA 13" please share!
