How is it native focused? it's obviously an HTML/CSS/Javascript framework. It's not native to the plateform itself, since you are developping in a webview.

it's basically some kind of Bootstrap + angularjs bundle. How is it more advanced than Sencha Touch for instance?
Sencha Touch is great, but Ionic has a permissive license with an open source spirit. Sencha's open source version is only for open source apps compatible with the GPL, which is a big restriction. And, you can actually submit pull requests and contribute to Ionic. Plus the development model of Sencha isn't markup based, and doesn't use Angular.
If you are happy with Sencha, by all means, keep using it. We are ambitious and will be working hard to make sure Ionic is better than Sencha in most ways :)
- It probably doesn't work in IE or Firefox, because it's focused on working inside embedded WebKit/Blink.
- It probably isn't appropriate for a "responsive" or "progressive enhancement" situation, because it's assuming it'll be in an embedded browser, on a known device, with js on.
When you see the word native, you expect native code. According to this framework, I can call any responsive site native.
