Presto Change-o, Opera Browser Shifting to Webkit Engine

Maximum PC: Opera Software today put the world on notice that its Presto rendering engine will be making a disappearing act. Going forward, Opera will make a "gradual transition" to WebKit, as well as Chromium, for just about every upcoming browser release for smartphones and computers, the Norwegian browser maker announced today. The engine replacement was mentioned as an aside to the fact that Opera's collection of browsers across all products now boast 300 million users.
