On last Friday I did my presentation using Microsoft Office 2010 Beta running on Windows 7 Ultimate RC (it was an informal one of course!). Transitions and object animations are revised since 2007 and they are all cool. I also noticed that many bugs which exist in 2010 Technical Preview were also fixed - problem regarding transparency of images, for example. Its experience was totally better than 2007 so far.

The only problem is that the Office 2010 is still a bit heavy. Sometimes transitions between slides were not smooth enough even on my Core 2 Duo laptop...

Anyway I'm looking forward to using the final release version.
