Comment 12 for bug 711561

This is terribly sad. Loss of the compiz cube is a MAJOR loss of functionality.
By not designing functions and features around it from the start, the developers have made a huge mistake.

I personally will have to stay with 10.10 until this oversight is corrected. I suspect many others will have to do the same.
This is NOT the way to grow Ubuntu's user base by taking away things people really like and use a lot.
Adding new features is great, but not at the expense of taking away things that have already proven their popularity.
