Not really. If you filter by the "App" category on OpenStore you get 18 pages of results and if you filter by "WebApp" you also get 18 pages of results. So, about 50% are webapps.
Because the filter you use includes all kind of crappy games. if you focus on other categories, the percentage is much higher.
Aren't most "apps" redundant considering you can install a program the way you would for a Linux distro? There are resources going back ages. I suppose they aren't designed for mobile, but could be tweaked.
