I've been trying out the trial version of Office 2004 for the Mac (and should have a real copy of it on the way very soon now). I have to say Microsoft has really done some cool things here. The project manager in Entourage rocks. It's the kind of thing that would be insanely useful to my ADDness. But there are a few things about it that I have to rant about. The first is that some kind of syncing between Entourage and Apple Address Book isn't in there. I read a nice post on this over at blogs.msdn.com by Dan Crevier that explains the reasoning, but it still annoys me. Thankfully there's a nice shareware app out there that does it called Sync Entourage - Address Book by Paul Berkowitz.
My next nitpick is one that I have with a few apps on OS X. In text fields, Cocoa uses emacs control characters for navigation. ^n, ^p, ^a, etc. Even ^k/^y. It's very handy for those of us who sometimes use those out of habit. The problem with Entourage is that it doesn't use these, and in fact those commands do other things altogether. I'd love to have a preference setting to turn that on if I wanted. I just find them much easier to use than the arrow keys. From a typing standpoint it doesn't require me to move my hand to another position at all.
Once I have the full version of Office I'll write up a bit more of a review, but so far it's pretty damn slick.
