If MS Office continues on the path they are going down, I am going to an alternative. They are dropping the price on Office for Mac coming out, but the catch is that there is no way to put it on more than one computer, and Entourage is no more. It would not too bad to see Outlook for Macs, but you have to buy the higher level versions to get it.
Microsoft does own the business world, there is no denying it.
I've installed DocsToGo in the iPad. Its counterintuitive but it works. You can modify Word, Excel and Ppt documents on the iPad and sync them to the PC. It does not have a beautiful interface but it gets the basics done. 14.99 is not expensive if you think about it.
All the Office apps that exist today have severe limitations and formatting issues.
