I remember doing some web development work for HardKernel/ODROID back in ~2010 and I just did it for free (I loved the idea of an "Android Game Boy," plus Chris Pruett at Google recommended it for gaming and game development[1]), and they ended up sending me an ODROID-S out of the blue. I was totally surprised and felt I didn't really deserve it (MSRP was like $200-300 and I was a poor college kid), and I'll never forget the gesture.

HK earned a longtime fan with that move for sure, haha. :)
