Well it looks like I will be the only one here that is going to wait for Office 2008. I use Office at the school where I teach and at the Guard unit where I work, so it is just easier to use a similar program whether I am on a PC or a Mac. I don't hate the product just because it is Microsoft. Office for Mac is a very solid, well designed program. If it was junk, I would probably switch and learn all the in's and out's of the new program, but it works well.
When I send my boss a file, I never have to worry about what is going to happen when they open in Office at the other end, because I know it will look perfect. This is just my opinion so don't go off on me for saying that a Microsoft product is good.
