The browsing experience for me is better with the new Opera Mini.
Mainly, though, I haven't found enough worthwhile websites that really require me to much browsing on my curve. When I have some free time I might use it to read the latimes or something, but other than that I don't really use the web much.
Who really wants to see entire web page on their phone? If you can get the info you need quickly without all the "glitz" and ads found on most sites, why would anyone bother zooming, scrolling, pinching, tapping, swirling, licking, or god knows what else?
I agree. The new Opera 4 mini beta has a cool mouse that can scroll & zoom which is nice (especially if you have trackball) but it takes 6x longer to do anything on it plus it's not BB menu friendly. The tech behind Opera 4 is impressive but I dislike the UI - no shortcut keys, space doesn't pgdn etc. BB browser all the way w/ BB emulation (WML & HTML).
I find that Opera Mini 4 is pretty good for several websites that don't render very well in BB Browser -- it performs very well on the 8700.
You just have to remember to avoid using the scrollwheel. Use the numeric keypad to scroll up/down faster instead -- much faster and you can hold the key to go to the top/bottom of a page very quickly in Opera. (2/4/6/8 keys). You can use the number 5 key to zoom in/out quickly.
Once you get the hang of using only the numeric keypad for fast-scrolling, it's very fast to navigate in Opera 4.
I do wish that Opera Mini was re-engineered to be BlackBerry UI friendly, it's more designed for generic-cellphone.
