Branded Utility is a great concept. Junta 42 points out that this is what Google do, but calls it content marketing. (It seems to me that there are quite a few people creating different terms to describe the same concept - namely, giving cool/useful stuff away)
Anyway, with that in mind I wanted to mention the Dyson Airblade. I first encountered the Airblade at the Sainsbury's Store Support Centre (that's what they call their HQ in Holborn. I like that they call it that). It was a revelation. When I found it in a pub I mentioned it to my mate Tom, who went to the toilet even though he didn't need to, just to wash his hands.
You should have a look at the photos and comments on Flickr as well - "the best handdryer ever!"
This is a great piece of design and underscores Dyson's value and approach perfectly. When there are other cyclone Hoovers available, what better way to demonstrate that yours is likely to be the best than by solving another seeming non-issue through great design? Hat's off. I also love their TV ad. That said, I have a £25 Tesco hoover my girlfriends parents bought for us...
