"Not a breakthrough - but a nice update"4.0 starson by getwired
Pros: Universal app (better perf on Intel Macs), Office 2007 file format support...
Cons: Entourage still a second-class citizen to Outlook, no OneNote or InfoPath
Summary: Overall, I'm really happy with this. I find it disappointing that two of the above reviews are completely worthless. If you haven't used it, don't review it. There is simply no other office suite on the Mac that compares. All of the open source office suites on the Mac have half-witted file format compatibility, and a UI that is completely confused - none are certainly Mac-like enough to be workable on the Mac.
I wish Entourage was Outlook, but for the Mac. Instead it seems like Outlook Express++ for the Mac. There also is no OneNote or InfoPath for the Mac - I wish there was. Oh well, another reason to run VMware Fusion. Finally, the best reason to upgrade (for those who blah-blahed on about why this isn't a good upgrade but open source alternatives are), this gives those of us with Intel Macs an office suite that runs well without PPC emulation.
