antadam..you may think they are "Major" changes..but there isn't too much thats too extensive thats been changed.
is exactly the same as a pre-existing program called Konfabulator. Konfabulator's website has 100s of widgets. Mac just wanted to create there very own widget program because they knew they were getting so popular.
Is a search feature that is actually available through another site that features Mac customization. It just adds a search feature to your toolbar..which does exactly what spotlight does.
Some other stuff like the Dictionary App and the Enhanced dock menu are just minor changes. A lot of other changes have gone into the system that you won't even notice.
I still think its well-worth the buy because I'm always down to support apple. But most changes you won't notice.
