i guess becoz Opera mobile works only on Symbian. so limited users.
But yeah Opera mobile is much more powerful than mini. Can browse just like i do on my PC. And with its awesome cache, even crappy gprs seems faster.
they don't use adsense. Opera has a contract/agreement on this with google. Google pays Opera for
a)setting google as the default search engine
b) every search . Its like some cents for every google search done through opera.
This even extends to Opera desktop. So if u want to help Opera, simply google!
yup. Only thisdo you mean using the built-in Search box
