I'm back from a LONG hiatus- I hope I still have a reader or two left.

So I read an article from Mary Jo on Office Servers. While I won't comment on unreleased products in a specific way, I wonder what people think of these concepts. For example, how would you use an Excel Server product? Are there things that you'd use the Excel Server for that you couldn't do with Analysis Services? How about an InfoPath-based server product? Why would you use this over SharePoint with a repository for InfoPath forms and saved documents? I'm interested to hear your thoughts on these concepts and to understand how you might use these products. Also, any suggestions on these products would be appreciated.
