So how do you carry your MBP then, in a backpack, by hand?
I carry mine in the nami aka foofbag, and alternate it with the Tsunami foofbag (I also have the Nishikigoi foof for my old Air I sold).
For the last 1.5 years since I'm a picky bastard, I've been carrying it by hand in the sleeve.
But that all changed Saturday when I ordered this (the machine will remain in it's foofbag within the sleeve (and if it doesn't fit with the sleeve, I'll pull my gray Tucano Second Skin into the rotation since that's super thin and I know it will fit):

I ordered the blue one, should have it in 1-2 weeks. Truthfully I like the Saxby Slim in brown the most, but I didn't want to deal with a messenger for work--I wanted useful handles and simplicity (may get the Saxby Slim down the road for an everyday bag). Despite this new bag, and keeping the MBP in a sleeve, you bet I will still treat it like a baby.
