I’ve been very happy with Opera Mobile on my Blackberry — it stands head-and-shoulders above the two browsers that came packaged with my Curve.
And a bit of fun news is the announcement of Opera Mobile 9.5 real soon now. And, of course, Firefox Mobile is due to come out later this year.
Mobile browsing is never as fun or easy as PC-based — but it is, of course, well, mobile, and anything that can make it easier is a definite good thing.
