I have been researching trying to find a small and slim messenger bag style for my new Alum Macbook. Lots of choices and got it down to my top 3: Booq Boa SlimCase M Tom Binh Ristretto Messenger bag Be-Ez LEVertigo Strongly prefer the slimcase for a number of reasons, but looking for real-world experience from anyone else that has used this with their MacBook. Is there much difference in fit between this and the Slimcase S90? Is the strap comfortable or need to be replaced (seatbelt material - no pad?). My objectives were: Vertical orientation Good laptop protection Slim size - 3" or less depth Good organization of pockets / focused on Mac (i.e. pocket for power brick) Good quality Good protection if dashing between buildings in the rain Not leather (weight) Not backpack I've been through all the threads here, and suprisingly very few (or none) were from MBA or MB alum owners. In fact, of the 3 I listed, very little detail or even opinion. Thanks in advance!
