In fully a year of reviewing gadgets and other manly bits and bobs, Microsoft (via PR firm Edelman) is the first to send me something in a re-usable shipping box. And, clearly, it has been re-used, over and over and over again.
(The item sent in is the new DSM-750 Media Extender from D-Link, by the way. First impressions are that it's much better than the last generation, but very much wants you to have Rube Goldberg's home network set up for it.)
Update: Lenovo sent me a test unit in a very nice reusable box. Shipping all this crap back to the manufacturers is half the reason I don't do more hands-on reviews than I do. It's such a hassle. Lenovo's got it down: slick little reusable box, barely any waste at all, and packed and ready for shipping in seconds. – Joel
