Their mobile browser was great on my Windows mobile device. It opened up a much larger percentage of the web to that phone. I didn't mind paying for it, because it was worth ever penny.
Users now aren't willing to pay for a PC browser, there are just to many that are free. It wasnt so long ago that Opera was payware, with an ad suported free version. I think those days may be part of the reason for the slow uptake now. There may be a lot of users out there who still think they will need to either pay for it, or put up with adverts.
Regarding FF, what exactly have they done from a marketing point of view apart from their dealings with Google, and that was very much a two-way street.
I still think Opera offrs a beter browser then FF and IE, but Like Brett said, they just don't know how to push it.
