Why are people still using phone gap? What's the point? Might as well just build a web app. PhoneGap is the Dreamweaver of mobile.
Unless it's changed a lot since 1.0 I don't believe it's some kind of WYSIWIG iPhone maker that creates bloated, terrible, code.
Phone gap is now a set of technical/busisness services for managing Cordova projects, such as Build deployable packages for all platforms via a web service
We advise native for productivity apps and such; day to day use apps should be fast and snappy, while promotional apps / marketing apps should look pretty.
It sounds like you make apps for people. Assuming you have someone on staff who knows iOS and someone who knows Android is it still faster to do it in PhoneGap? We attempted a phonegap app which ended up failing because of performance reasons. We rewrote the app in native iOS and it didn't take nearly as long as the original phonegap did with the constant tweaking in an attempt to get it to look and perform acceptably.
And the Phonegap experience isn't really good unless you spend a huge amount of time. Webview is just not very good; you need something which is native but crossplatform to replace it; everything we tried so far (appmobi, appcelerator, rhomobile) actually was worse than Phonegap/jqm to get right. But we keep at it as we know what our clients want.
Often the Phonegap version is treated like a prototype; then the client saw it and knows what they want; after that they have it rewritten to native on the platform which makes them the most/gets the most attention (etc). Which is almost always iOS by the way.
