I'd have to say that upgrading from Maverick Meercat to Natty Narwhal has not been a delightful experience.
It's not because of the new Unity interface - on the usability side, it's because I think they took it out of the oven too early.
I have found at least 2 major shortcomings:
1. Unity window management stability is below par. Unity doesn't seem to work well with a number of Compiz settings. I have found odd behaviours such as the mouse-click not working intermittently; the top bar of windows disappearing altogether; etc. The advice is to restart Unity or restart Compiz - how about fixing it instead?
2. LibreOffice. Now you would have thought the LibreOffice team would like to have really shown up OpenOffice - particularly as Canonical now packages their suite instead of OpenOffice. However, if you edit the newer format Microsoft file formats such as .docx - then beware! I have found that LibreOffice is very limited in reproducing what the content looked like when open with the relevant Microsoft Office function.
There may be other limitations or improvements, but the above problems stand out for me in that what I have is a backwards experience when compared to the previous release.
What do I suggest?
If you want to stay on Natty, then simplify your Compiz settings. The next action is to remove LibreOffice and install OpenOffice. I strongly suggest you install OpenOffice by downloading the Deb package from here. Then follow the installation instructions from here. Although the installations instructions are for a previous release of OpenOffice - they still work fine with 3.3.
Let's hope Canonical addresses the Unity shortcomings quickly and that LibreOffice lifts their game!
