Application must be able to run on a mobile device and run in a browser (more marketable)

If this is required, why not just do it thin with DHTML and JavaScript.

I don't know if browser apps are more marketable - I do know that most of those kinds of projects are being bulk produced off shore.

You would have to agree there are a lot of features that we can offer on a desktop app that we cannot even begin to offer in browser apps. Then there is speed and multiform syncs. There are good browser apps to be sure. The UT is one for example. It really depends on what the app needs to do.

I think a better measure of the relative strenghts would be to show that a browser app can do what a well pedigreed high end VFP app can do - rather than other way around.

What you need to show it seems, is that what you are advocating can do what a sophisticated VFP app can do. Unless, of course, you already have something very cool you would like to challenge an experienced VFP developer to mimic.

In that case - give us a URL!
