Hmm – OneNote Web App works well in Firefox 4 for Android on my Samsung Fascinate, at least from an initial glance
That’s one reason why I’m in favor of browser competition being as healthy on smartphones and tablets as it is on computers. On iOS, that’s not going to happen anytime soon–Apple doesn’t permit full-blown browsers with their own rendering engines in the App Store. (Ones that use the Safari engine, such as the excellent Atomic Web Browser, are permissible; so is Opera Mini, which does most of its work on Opera’s servers, not on your phone.) On Android, however, there’s nothing stopping other companies from competing with the OS’s built-in browser. Opera announced new versions of both Opera Mini and Opera Mobile for Android a couple of weeks ago. And now Mozilla has released the final version of Firefox 4 for Android.
