Meanwhile, Eden 1.5 - Notion Ink's UI and multitasking system - is going out to existing owners later today. It'll also include new apps, though exact details won't be revealed until the new firmware is released. Apparently Honeycomb will follow on come June 27, complete with hardware acceleration.
If you want to place an order you'll first have to subscribe to Notion Ink's list, here; the company is sending out ordering invites now. Of course, the Android tablet landscape has changed plenty since we first saw Adam, and it's no longer the first Tegra 2 slate around.
