I've been using Opera Mini Beta 2 for a while now, it may look slick, clean and efficient but, I still find Opera Mini 4.2 a more functional application. There are no feeds (I love my feeds) in the "new" Beta and Opera Link doesn't seem to work. Downloading has improved in that you can now choose your download location. Very handy indeed.

I've just tried Opera Mobile Beta 3 and I'm blown away. While it may look similar to Opera Mini Beta 2 it (in my opinion) runs smoother but the catch, like all versions of Opera Mobile is that it loads the entire web page. That's not good if you don't have a data plan.

Due to the different methods that they use to download data and display webpages I guess you can't compare them. Apples with oranges. Mobile downloads the page to your phone, converts it, and then renders the page. Mini has the page converted at it's server then the compressed page is downloaded and rendered. The main reason why I'm impressed is simply because a stock trading website which I use nearly hourly now works to near full functionality, something I couldn't get in any version of Mini.
