Hmm, I applied twice, from http://www.google.com/chromeos, and from the link in the dev version of the browser. I wonder if that will actually hurt my chances of receiving one... :/
I'm not sure if it does or not. I did the same thing. Since the applications were so different, I figured I would fill out the general one on their website in addition to the one linked to from within the chrome dev build (I used the same Google account for both applications). I got my Cr-48 this morning, so it must not have counted against me too much.
I did the same thing, but first from the browser on Tuesday. Instant regret for filling out both, but the longer form has a lot more info that I thought they'd like. Either way, something worked. It showed up today.
