(image source) It's very important for me to choose a HTML5 Mobile Framework : performance (slide and loading speed) Most framework works well on Android 3.0 and iOS. Andorid 2.3 have a big market share, But for Android 2.3, it sucks. If a mobile framework works well on Android 2.3 , most Andorid can run well. However, there are many and many HTML5 Mobile Frameworks and lack of performance comparison. So I test by myself and use 3 level to classify. You can do it by yourself if you need more detail.
