Unfortunately, I have gone back more than disappointed. The advertised improvements from 2008 are actually nonsense and limited primarily to a graphical update of the UI, since you can also save money.
But worse: The Word Performance is greased catastrophic. At 5000 words 2008 came into bucking (with graphics) ... 2011 already at 2000+ (no graphics). I can tell so, are that the new oh-so-great (Web) features sloppily implemented and easy to eat too much resource only.
A reasonable smooth working is therefore for longer texts hardly possible. I am disappointed plentiful.
The only plus point is the nice full screen mode, there are also drawbacks: Where can I please there (without the keyboard shortcuts by heart knowing) insert footnotes, references or graphics .... simple ridiculous like that. Previously everything went with the Toolbox that is now but limited in its functionality.
Nor is it possible to adapt the new menu bar or to change what is just ridiculous.
In addition, when the multi-touch support is for the zoom ... I know this may not even have pages but I just see no reason not to add ...
Best Regards!
