Rick's expectation is that mobile apps will use HTML/CSS/JS served from "whatever"- in his case the MS stack though he's right that it could be anything if you're using HTML/CSS/JS. I agree that HTML/CSS/JS is becoming as much a standard as SQL so it makes sense to use it, not so sure about mobile apps always being served or deployed in a browser. As per previous posts there are numerous vendors who earned their billions from served web interfaces (e.g. ebay, priceline, godaddy, amazon) who nevertheless promote locally installed apps for mobile devices. Why? Perhaps it's temporary pending 100% reliable mobile networks- though the niche experts assert that there never can be such a thing.

FWIW, this uncertainty is actually an attraction of Lianja: HTML/CSS/JS already, plus a clear path ahead no matter which way the market goes. The big difference for Lianja users will be cheap local deployment versus potentially expensive server licenses.

Lianja's remarkable capability with existing VFP code is a bonus IMHO. Why not dig out some of your retired VFP code, point the beta at it and see how you go. Then check out the python and JS and ask seriously where is the downside- apart from abandoning employment opportunities in the MS stack space, which makes sense for some people- even some of the ones who were very early adopters of FP and enjoyed a heck of a ride as a result.
