Opera has tough competition in Skyfire among other browsers that are more advanced when it comes to video playback. That is why it is critical for them to equip the new software with Flash. And the consumer version of the browser is expected to have all of the same upgrades seen in the enterprise version along with a new widgets manager. Opera Mobile 9.5 has been called a true challenger to Safari, and considered among the best mobile browsers available. The addition of Flash can only improve it and bodes well for the abilities of the consumer version when it is released.
