Here is a link to a review I just posted on my Mobile Learning in Higher Education blog on the Ristretto for 11" MacBook Air:
Review: Tom Bihn Ristretto for 11″ MacBook Air | iPads in Higher Education
I have been using the bag for the last three weeks as my EDC and am overall very pleased with the smaller size and yet all that it can carry. Right now I'm using a 3D Clear Organizer Cube for my power supplies, cables and flash drive; a small Padded Organizer for my external SSD hard drive and a Clear Organizer Wallet for cash. This week, I've started carrying my Fuji X100s camera and have been shocked how much room I have, yet don't feel loaded down.
I just back from the post office where I picked up my new Smart Alec :). I'm planning on using it as a camera bag when I travel on longer assignments. I'm looking forward to getting it set up and will be using it this weekend for a photo assignment I'm doing.
