It seems the Notion Ink video demo floodgates have opened, with the start-up following Saturday's Adam walkthrough with new footage showing the Eden UI. Notion Ink's own handiwork, Eden is a system of side-swiped panes each filled with a single app, together with a red cross-bar launcher for easier task-switching.

The panels can be re-ordered by dragging them around, and there are various views on offer. Best of all, even if the panel is on-screen, if you're not actively using it, the app doesn't make demands on your system resources; that means that, even though you can have multiple apps open at once, it won't put too much of a strain on the Adam's Tegra 2 processor.
