Opera turned to be the everbest browser among mobile devices. see the statistics

Here leftmost Redbar is for opera, iphone , Nokia and Android is the immediate competors. ( courtesy : statcounter), and ofcourse this is a worldwide trend.
The reason behind this immense popularity is nothing but its cross platform compatibility and its uniform nature in all platforms. and in my experiece its continuosly delivering features with each releases. This time opera mini 6.1 comes with a lot functional and appearance enhancements never before.
before looking deep into opera mini, there is one more application alongside, Opera mobile. , this is somewhat same as opera mini. the difference between the two is where the pages get initially downloaded., ( both uses Presto browser engine)
Opera mini uses opera mini server to download the site and to translate it for the client device. it costs less for the client device to get a mobile friendly version with this browser and for sure the application weights less as major functionality resides in a remote server.One more advantage here is server side updations will advantage the user with out a single click
Opera mobile function as a self existing browser in all sense. this acts exactly as a desktop browser , transalates all pages as its own duty, the client server communication is not present here., This version is opted by handset manufactures for pre installing the browser with their devices
this version is available only for Nokia, Android and Windows mobile
Features ( same for both )
1. Speed dial
Just like google chrome it got a speed dial screen to access favourite websites with a single click

adding to speed dial is simple, click on any Free + button for detailed option to add
