Even though it is used by 160 million people, Opera's position on top of the mobile browser list was grabbed by the Android browser strictly on the popularity of the open source OS. Thus, Opera felt the pressure to update the browser and has added more features such as unlimited bookmarks versus the previous limit of 9.
In addition, Opera continues to claim that Opera Mini can save users money. The browser works through Opera's servers and compresses a web site before sending it to your phone. The process is faster than if your phone did all the dirty work and rendered the site itself. Opera now claims it compresses web sites by up to 90% saving you more precious time for receiving and sending data. The new version of the browser also pans around sites faster than before.
And the latest data from StatCounter shows that Opera is back on top, once again forcing the stock Android browser to eat its dust.
