Thank goodness some people finally came to their senses. The "AirMail" manila sleeve for the MacBook Air was cute when it came out, but please--it's actually sold out?
The "Air Manila" from Civilian Lab is a much more sophisticated version, dressing up the envelope concept with hand-stitched leather, Tech Digest says, as well as a padded interior and air vents. That should help keep it from getting mixed in with interoffice mail, which is important because the anorexic laptop is accident-prone enough as it is.
