Bert,

That is VERY helpful - I really appreciate it!
If we were to go with the client/server arrangement, and got a low-to mid end Dell server with the foundation setup, is that what you were talking about above for about 700 bucks? Is the OS included in the Foundation setup? Does that include everything we would need?

With regards to the "want list", do I have the correct general idea here:

Dell server PowerEdge - about $700
Windows SBS 2008 Premium - $ 1899

How is the Foundation setup OS different from the SBS 2008 OS?

With regards to the SBS 2008 OS, would we be better going with the standard or premium version, in your opinion?

Having someone set it up is not as much of a problem for us, because we have IT people available. But I trust a computer-savvy working doc more than them as to what is best for what we might need. You are familiar with AC, they are not. They can hook up the wires and install everything. I agree, I think wired is best. The only wireless would be with the netbook/laptops that some might choose to use...

Thanks again for the advice!
Melanie
