Just be aware that some web addresses can't be typed in with Opera Mini since the keyboard doesn't interact properly with the browser. Some letters will come up as numbers and I don't think you can intentionally put numbers into the web addresses...they only happen by accident when trying to put certain letters in. It may take awhile before you experience this. It took me a couple weeks and then I went insane trying to type in a certain web address. I was never able to do it.
Also, you will find that it's almost impossible to click on the right thing sometimes. For example, in forums if there are threads with multiple pages and you want to go to say page 4 out of 7. Good luck!
It is fast, very fast, but only good for basic browsing, in my experience. I hope they come up with a version that's actually for the Storm soon!
