> That's why I'm wondering what customers do that upgrade applies to?

Denis;

If you upgrade to VFP 8, simply inform your clients that you will do all future fixes or add on requirements in VFP 8, and have to charge them for the additional work involved to make code changes, debug, and re-compile . Microsoft is looking out for all developers. You will automatically have people pounding on your door the day VFP 8 is released, “I want my application re-done in VFP 8.0”! Watch out for the rush and I hope you can handle the extra work.

At the same time for those third party add ons that will not work with VFP 8, that will help the industry also. You will have to purchase new upgraded add ons and that will provide additional revenue for the companies involved. This is truly a win-win situation. :)
