Dan Kasun discusses a concrete example of Software + Services:

In my last blog, I discussed my perspective of what "Software + Services" means - to sum it up: coarsely grained business services that are interacted with via client applications (in some cases, multiple types of client applications).  Gee... I should've kept it that brief on the first blog.

The best way to demonstrate S+S, though, is to look at a real example... and Microsoft just came out with a doozy: Microsoft HealthVault - www.HealthVault.com
