I think part of the reason the web beat native desktop apps was the notion of the app being "available everywhere". This certainly made web based mail clients the initial killer web apps. Native mobile apps don't suffer from this as much given people carry the app with them wherever they go. As well as the prevalence of cloud based apps we're seeing native apps for each platform interconnecting. Certainly the ROI for building a single web app rather than two or three mobiles apps is better, but I believe at the moment the UX is better for multiple native apps.
