Another problem - change for change's sake. They wanted to push a new product, so they changed stuff that was perfectly fine. A lot of this ended up being cruft and eyecandy that was just unnecessary and annoying. Microsoft is laden with this problem now - Windows and Office are technically very stable. How they break away from this will be difficult/painful.
