I like opera mine 5 beta cause it's way faster than BB browser for me but the functionality of it just doesn't compare. After a little 5.0 love I'm hoping there is no need to have anything but the BB browser

The berry browser that the phone comes with does the job just fine for me. Sometimes it loads a tad slow, but usually it's pretty quick. I tried opera and just saw it as a waste of memory really.
I use all three browsers, Opera, Bolt and the Blackberry Browser. Depending on what you want and need to do will dictate which browser to use. To download anything OTA, the BB Browser is necessary. Opera has become the default for links from texts and mms's. Some webpages do not render correctly in Opera (USA Today) so I use the Bolt Browser for those pages.
