HTML5 support on the new Symbian Anna falls short
Maximiliano Firtman, a respected developer, had the opportunity to put the new Symbian Anna through its paces. On the plus side, he points out the new features of the Anna browser, including multi-window browsing, and enhanced CSS3 support for gradients, 2D transformations, transitions, animations, and media queries. Overall, Firtman says the browser is indeed faster.
But when it comes to HTML5, which has become essential to browsing, Firtman was disappointed. Symbian Anna's HTML5 support excluded Viewport support, audio/video tag support, offline storage cache, a geolocation API, and an accelerometer API.
Of course you can use Flash on Symbian Anna, so it's not the end of the world. But Nokia customers shouldn't be made to feel completely neglected, now that Nokia's moving on.
