I have not used unity. [yet] just too comfortable with gnome.
but it sure looks as if windows 8 will have everyone scrambling in the "new os / new hardware" musical chairs game.
another round of perfectly fine hardware cast off for the latest and greatest. given that Ubuntu traditionally works very well on the last gen hardware, I will be glad to see the re-purposing and reuse of older hardware continue to keep generations of working hardware from the land fill.
Ubuntu, good for you and good for the environment too.
