I hate to be a pessimist, but "call me when it ships." I've read so many articles about "iPad killers" (before and after the iPad launch) that I've become entirely desensitized to their promises. I feel a great deal of reservation about rewarding companies with my time, attention, and admiration until they ship an actual device.
I'm interested in this device mostly for the Pixel Qi screen. Luckily some other tablets are coming out that will be using that as well (supposedly), but the Notion had the most interesting feature-set of the bunch. The amount of hype followed by absolute silence is getting to be annoying, though.
