When I was using OS 4.3 I used opera mini for a handful of sites. But I like the BB browser interface better. If you set your settings according to that previous post, especially on 4.5 there won't be very many sites that won't render properly. So far only two sites I have encountered like that, cnet and netflix, but both also have problems in opera mini. For cnet the post comments part doesn't show up, it does in opera mini but you won't be able to log in to use it. And netflix duplicates the nav banners and buttons in both browsers.
