I am impressed.
I am surprised to find myself impressed with a Microsoft product. I vowed I never would be, but I have to admit that the Macintosh Business Unit of Microsoft has truly released a must have product. I bought the upgrade as soon as it came out and so far it has only crashed once (while doing an import into Excel). If you have Office v.X then I doubt it's really worth an upgrade. Unless you see one of the new features as a must have v.X will work well for quite a while. However, if you use another product I must impress upon you how wonderful this suite actually is. The new project center in Entourage is very handy if you have problems with keeping files together and the new notebook view in Word is especially useful if you often take notes in meetings. Presenter Tool's in PowerPoint is also a great feature. Messenger is useless, but you already have iChat so you don't even have to bother with it. I have found that all of the applications feel more "Mac-like" with a more appealing interface. While a completely Apple built suite would win me over, I doubt I would be satisfied with any other companies product. If you are in a business or academic environment, then this product is a must have. So, while I think that all of the rest of Microsoft's products put together are worth about $5, this is simply a must-have product unless you already have v.X.

Another "perl" from Micro$oft
Well, this much phrased "office" is another ugly buggy full of crap Microsoft "product". It consistently crashes, It uses some idiotic algorithm for tracking grammar that makes it HORRIBLY slow. Removed this garbage from my computer and use Nisus. Much more convenient program and by far more reliable. If you need the REAL grammar checking take Grammarian! It is the real stuff!
I maintain the policy "NO MICROSOFT PRODUCTS ON MY COMPUTERS". I ignore them completely and I have no viruses, no security issues, I don't have to deal with zillion buttons etc. Let me put it this way: you have wonderful Apple box, what is the reason to put this PC garbage on it? Enjoy the real software, good programs and creative mood!

Basically a waste of money
I thought the previous version looks better and even works better. I noticed only very few minor changes that didn't make this one better for me. But may be it's just me...:)
