I think a good way or restating your point is that, the better web gets i.e. more advanced frameworks with better testing suites, the harder it is to screw up.

I think a good way or restating your point is that, the better web gets i.e. more advanced frameworks with better testing suites, the harder it is to screw up. A point I'd like to make: At the end of the day though, mobile _can_ be fast, but it just doesn't compete with native, yet. When I take a web project after concluding an iOS app, I miss being able to run tests and deploy to my phone or iPad in one place and easily. I miss how formal native code feels over a javascript stack. I hope this changes one day, and I love what Firefox OS is promising, but until then, I will be working with native solutions.
