I'm glad you dig it!
Going with the hubs as our promo item was a bit of a gamble since there is no branding till you plug it in, but my AIM and ICQ has been lighting up all day so I'm guessing other people are discovering them too.
I figure they're more than just a cool give away, they're something almost everyone can use. I'm using one right now ;)
Love to hear feedback from everyone on these.
