Well.. I think there might be potential for an actual 3d environment.
The more I think about it, the less sure I am of that. There are a few places where 3D
visualization would be useful, such as CAD or medicine. I'm not sure how it helps on the desktop, ever. We've had centuries to revolutionize our physical work environment and have mostly come up with 2D interfaces-- desktops, paper, keyboards, mice. Everything is flat.
We do stack storage-- shelves, drawers. We pile papers. I'm not sure that qualifies as 3D though-- or that the existing folders-within-folders, icons-on-icons metaphors don't offer similar utility.
There are places where simulated 3D offers a unique capability: I like how fast user switching indicates a change of context. I kind of wish that technique had been used for Spaces instead.
As crappy as 3D displays are, I'll be amazed if it really offers a better way to organize information than we've managed in the physical world.
This is absolutely lunatic. BumpTop was one of the little guys I was rooting for, and they made a really cool useful product. Now it's going to be yet another endless Google Beta.
I've been frustrated by Google's lack of focus too, but if you were rooting for BumpTop, then be happy-- they were successful. Often the reward for success is acquisition. They made their fortune. I'm not convinced this is going to be a Google product-- sometimes companies look at these types of products as living resumes. They've proven what they're capable of, now Google want's access to that talent.
