Forbes has a story on Must-Have Mobile Software, but Opera doesn't seem to be mentioned at all.
The author does mention browsers in general, though. She doesn't like them.
Mobile browsers are getting better, but can be a pain, especially if you aren't paying for an ultra speedy cellular data connection.
It doesn't sound like she has tried Opera Mini, which is surprising for a list of "Must-Have Mobile Software", seeing as Opera Mini has frequently been mentioned as a must-have by other publications. Opera Mini compresses pages before displaying them, which means that it is faster, and costs less if you don't have an unlimited data plan.
I wonder if it would be worth trying to contact the author, Rachel Rosmarin, about this. Perhaps she is simply not aware of Opera Mini or even Opera Mobile?
On the other hand, she does seem to like widgets, which will make her happy with Opera 9 for Mobile when that becomes available.
