I'd think most roll their own apps, framework or no framework. But yes, there should be one alternative for no framework and another for native development. To your other point, if you look at frameworks like jqMobi and a cpl of others there really isn't much bloat. You can further remove functionality/widgets (or just don't call plugins) you don't need in your project. You mentioned the FB and Twitter apps. Thing is, it's not less code there, just smarter code and better design. They employ some gifted and smart ppl.

... or appMobi/jqMobi. You could basically use of any of these frameworks/libs and run your project through appMobi in the same way you would run it through Phonegap.

An open source object-oriented JavaScript framework for mobile or web apps from HP. Powers webOS

Of the above, only Titanium at times. Others are Enyo, jqMobi/appMobi, iui

This is just what the doctor ordered, for me. Been searching for a lightweight pure framework that plays nice with other mobile app dev frameworks. Looks like something I can wrap my head around. Someone mentioned it earlier, this got just as much to do with mental models.
