What's really great about this business is that the customers have some really intelligent and thoughtful suggestions. I listen even if I don't respond.
I think in the future, the path for upgrades will continue. It's just a little early to see who and what will be involved in the upgrade business or even what the technology will be. But what I did see, is that it was too early to drop the ERR product without something else to jump to. My hope too, is that I can be involved in this evolution. But one never knows, you can just keep yourself open to it and positioned for it.
I want to take this opportunity to thank Jon Z. Without his invention and creativity, we wouldn't be having this discussion.
