>"Curious - do you see price as being the only differentiator?"

Perhaps it's an approach unique to me, but pretty much, yeah. If I can define exactly what I need in a service, and the service provider can assure me they can meet those demands, it's all about price.

Which was my point with regards to ADP. It may be clunky and unpretty, but it does what I need it to do: pay my employees, accurately and on time (disclaimer: I hope, still in implementation!). Flash and prettiness is nice, but if it's superfluous, it has to be free.
