CES is, by its own admission, a trade show. It's more about attracting investors than generating buzz among consumers. Few if any of the devices there are actually in production, which is why it's bizarre that Notion Ink is supposed to unveil the Adam there. (especially since, as Android Police pointed out, they're not on the list of exhibitors at CES 2011)

Generating a buzz among consumers is better accomplished by sending devices to trusted reviewers.
