I think I’ve seen that somewhere before. Just not in the real world. It’s a fun and nerdy way to protect your laptop, holding up to 15.4 inches, inside. Others will recognize it and have a little chuckle as well.

It’s a bright yellow case designed like the virtual folders on your hard drive. It may not let you rest your head like the Napbook laptop case, but you can’t have everything. Comes complete with pixilated cursor-pin. It can be had at ThinkGeek for $29.99. I’m cool with it as long as they don’t bring too many things from my computer into real life. I’d like to escape such things once in a while.

Jobs and the Apple marketing team have been using a manila envelope to show off just how thin the new MacBook Air really is, but Belkin thinks it has a little bit better carrying case for the new notebook. The new MacBook Air Sleeves come in four different designs ranging from $39.99 to $49.99 that add only slightly more bulk than the Jobs’ envelope.

The sleeves are made from Neoprene and leather and include the Slim-Fit, which has no zippers or magnets, just a sleeve and a flap for $39.99. The Neoprene/Leather model does have an asymmetrical zipper for side or top loading of your MacBook and goes for $49.99. There is also a Vertical Sleeve model with a strap which is designed for use all by itself also for $29.99 along with the Expression Sleeve which also features a strap. The other Sleeves are tailored a little more to be carried inside another bag.
