Difference between Opera Mini 5 and Opera Mobile 10

 
They have 2 stuff in common:

• Both are based on the same core technology, the Opera Presto browser engine.
• Both use the same cross-platform user interface and provide similar features and browsing experience for all users.
  

And the difference:

• In Opera Mini the Opera Presto browser engine is located on a server while in Opera Mobile, it is installed on your phone.

Opera Mobile 10 beta: Verdict

First Glance:

This is just opera mini 5 beta with a different name and packing 10

times the size. Mini had been somewhere around 400kB in size but the

Opera mobile 10 comes in at around 4MB. Most of the transition need

have been refined. But sadly i still haven't been able to fine the

synchronise button.

Upon trying to load orkut on my Nokia N95 i was bombarded with alerts
of Low memory even though the Opera browser was the only active app.
And orkut didn't load either. Later i tried it in the turbo mode with
images off and things seemed better until the 3rd page when i started
to run out of memory again.

Compared to the mini, data transfer rates are huge even with the Turbo
feature on. And in my experience, this has resulted in a sharp fall in
speed.

Final verdict: It sucks. Doesn't even come near in providing a good
web experience.

Free App: Opera Mobile 10 beta

Opera Mobile 10 beta has been released for all, for Free! This is the

first time that Opera Mobile has been released for free, it's probably

due to the beta tag which means some bugs are still waiting to jump on

you from within the browser.

There are some pretty new features in this version of the Opera
browser. The best is the upgrade of Operas servers a new months back
coupled with the new rendering engine on the new Opera providing a
performance increase of almost 50%. The interface has also got a
revamp and is much smarter now. Check it out for yourself !
