Interesting read. Maybe I've been living under a rock, but this is the first I've heard about elementary.

Though, not directly related to their payment model, I wish they would more clearly state that they're a Linux distribution based on Ubuntu. I couldn't "quickly" find any info on it anywhere on their site, so I had to find out from Wikipedia. I guess this has something to do with their target audience, and the way the sell this as an alternative to Windows or OS X.

Somewhat related to their payment model, I would very much like to see them contribute some of what they're making back to Ubuntu/Debian, if they don't already.
