Like many others, I downloaded the new v3.0 OpenOffice recently. There are some things I like....some I don't like but all in all it doesn't seem that different than v2.4. For example, there are newer, more modern icon sets - but I thought the old ones were fine. Looking at the configuration panel, I can change my icons back to the old sets. In fact, there are 4 old sets and only 1 new set. Other minor changes include modern highlighting in Calc, a better looking progress bar during "Save." All in all, not much is different.
I like the fact that v3 has MS Office 2007 support. I can't begin to describe how many files I am sent in Open XML 2007 format (.docx .xlsx .pptx etc.) and now I can finally get rid of that 3rd party converter tool. It would, however, be nice to save in this format...though I suppose it is not necessary.
I really dislike that my custom settings did not transfer to the new update. My name, company name, address etc. all went over fine, as did my updated memory settings. But, ALL of my keyboard shortcuts, toolbar configurations and custom styles did NOT transfer! This was extremely annoying, especially since OpenOffice and the open-source community in general are strong proponents of customisation. They should most definitely have been transferred to the new application.
All in all, nothing to write home about, they could have called this v2.5 or something comparable. It probably didn't even deserve a blog entry :)
