Virtual Desktop
All the ideas and discussions
untethered windows, not constrained by desktop size
all desktop applications can be treated as individual windows floating in a virtual environment, and be arranged to ones liking, whilst not constrained inside a monitors height and width.
ideally, like window tiling apps like Aquasnap, you would be able to constrain, tile or otherwise organize windows as you see fit. Anchor them to a point in space, anchor them to each, anchor them to the surfaces of the 3d space you are in, spread them out evenly across your space.
for me, one obvious use is to be able to have tweetdeck stacked next to a game or film, and perhaps have tweetdeck's window be an arbitrary size if say, i only wanted to see one column, then i could just make tweetdeck's app narrow and tall, and then snap it to my other app, say, VLC playing a movie.
