Opera faced the problem of being a "commercial" browser until a short time ago, which hampered its adoption - they now have to make up lost ground.
I have Opera installed, but seldom use it, as FF has the extensions I need. Opera definately does render faster and has better caching, there's no doubt about that, but it's still a "closed" platform, which also hampers its uptake amongst web geeks.
ie is well, it's just ie - still the dominant browser, so you unfortunately have to use it on the odd occassion - the only time I use it now, is testing web designs.
Installed the ie7 beta this morning, taking it through it's paces - it's just not exciting anymore.
There was a time, a few years back, when new browser releases were such a big event on the net, I think it's good that they no longer are - in terms of web standards and content being king - but I miss those heady days of the net, when changes between browser versions made a profound impact on the web.
What we have now, in thier place, are improvements in content/content management and basically, heading to full online applications via a web browser interface.
Still exciting I suppose, but I now have an extreme headache after coding for 11 hours trying to support the various quirks of so many damn browsers, not to mention making sure my code is standards compliant and has AA accessibility - frikkin' nightmare !
