However, on mobile devices, this style of animation programming can have subpar performance and consistency – we wondered if it was due to poorer timer implementations.

HTML5 Scorecard: RIM BlackBerry PlayBook OS 2.0

Notably, it features the first HTML5 color picker input type that we’ve seen on mobile, advanced SVG filters as well as a perfect Acid 3 score.
