Yes, 2007 is / was an anticipated version.
Yes, it has a lot of features that make it a useful upgrade (not the least being the hugely increased worksheet size)
No, lots of people won't be upgrading soon because it's a chicken and egg thing. 95% of desktops have Microsoft Office. The new formats are not compatible with the old, so until the major corporate and government sites switch, compatibility is a major issue.
I will be upgrading very soon. I have the software but don't have it on my machine yet. Did install a couple of weeks back, side by side with Office XP, but I picked up a worm that caused me hassles so I just reverted to a pre-2007 image. I will most likely set up a dual-boot system to handle Vista and pre-Vista sided by side, but I know of a number of people who have Vista and an earlier version side by side on the same partition, and have no problems.
So, sorry that you are disappointed with the response from this site but many see good reasons for staying with what they have for the moment.
