FYI, what I heard back from Timbuk2:
Hi James,
I totally hear you! Quite a few people have been calling in looking for extra small laptop sleeves lately. I’ve forwarded your request on to our product development department. We don’t have anything similar coming up soon, but hopefully we’ll add an extra small sleeve to our repertoire soon. Customers have told us that our Eula tote is perfect for carrying the new super small laptops: http://www.timbuk2.com/tb2/products/bagbuilder/custom-eula
Thanks so much for the suggestion!
Best,
Megan
