Finally, we’re going to get a *real* solution that companies can use without the worry of what Google are doing with their data. It might not be free, but I’d prefer it that way, I’d feel I would have some degree of ownership of the software if I paid a subscription, for example. Even better, I should get my subscription free with my licensed copy of MS Office.

MS Office is what the business world uses, and having cloud integration will be very beneficial (Ozzie is a genious – despite disenfranchising users with the ribbon interface to 2007). Office Live does documents, Mesh does collaboration and files, Live does email and XBox Live gets it all in your living room. I don’t see Google competing at all those levels. The API is open, enterprise tested and thanks to the strength of .NET developers have next to no learning curve to get started.
