This nicely sums up why we're all banging our heads against a very hard wall. Microsoft will simply succeed by doing nothing other than dressing it in a new frock, charging more, and piling on the marketing BS.
Please read the rest of this thread.
It doesn't run faster. The UI isn't better - in fact it's more confused. And there's important features that aren't available in Office 2008 which were available in the 2004.
Office 2007 & 2008; codename "Revenge of the Paperclip"
1) It does run faster on Intel Macs (and more stable). Do your research, and if you read all the pages, someone in Beta made the observation that it is much faster than 2004 since it is UB.
2) The UI is actually based on one's personal preference. From my research, it is cleaned up a bit from the 2004 version (aka improvement). The ribbon stuff doesn't bother me one bit.
3) They have not increased the prices. They are exactly the same as the 2004 versions.
4) They removed VBA, and I can see why people complain. However, I do not use the VBA stuff myself, so this is negligible to me.
5) I can't complain at all about the price especially since I got it coming for a grand total of $57, cheaper than iWork '08.
6) I have read the entire thread (and have not based my opinions on these mere comments, but have done my own research). Most people in this thread complain about the lack of VBA in Excel and the fact that it's by MS and not Apple.
There are new features other than the fact that it's UB, but how many new features can you really add to an office suite these days? Each iWork release doesn't come out with amazing new features that make me want to pay for a whole new suite (except '08 finally added a spreadsheet app). IMO, iWork '08 and Office for Mac 2008 are both very capable. Personally, I prefer Pages, Excel, and Keynote when looking at the three big programs offered in the suites. My wife prefers Word (basically because she's used to Word), Excel, and Keynote. Based on the compatibility I need with MS Office users, I prefer the Office for Mac suite for my daily use, though.
