I'm sure you're wanting to make a point... But all I see is different browser chrome, and some browsers not requesting the mobile page?
Or - likely alternative - am I completely missing the point?
Yes all of these request the mobile page. The big problem with html5 development I find is that mobile phone developer have no reason to make browser good enough so that web apps can compete with mobile app. I mean why would they intentionally undercut their own business.
The problem with apps is having to download them. HTML5 is way better for applications that have single time use or where you want an interaction as quickly as possible.
