For those who were unsure of this at first, the changes are truly awesome!! I'd still like to see a USB keyboard for it, but I didn't have too much trouble typing this either! BRAVO OPERA AND BIG N!

(NOTE: The below was added AFTER I got back to my PC)
From the get-go this final version is impressive. The menu driven opening screen is wonderful. Connection times are VASTLY superior to the test version. The ability to zoom in and out has been enhanced, as well as text readability at even some of the smaller screen sizes.
I'll admit, without that keyboard, typing is still an issue BUT the new Wiimote keyboard pointer is steadier, less "jerky" than the original. However, with all the new features, playing existing flash games on this thing just took a step up as you can now hide the toolboar and adjust the screen (I would think) to be comfortable viewing on most TVs. Case in point: Orisinal's site never really displayed well, the icons were much too small. However, just a couple of plus button clicks on the Wiimote and they are fine, without becoming gigantic!
When one considers who this browser is designed for, Opera and Nintendo have really done a fine job with the final version in my opinion. So much so that my Mom, who wanted to get internet access at home for email and such, may find her son suggesting she think about the Wii as the browser is free for now and cheap as heck after June 31st (she does not have a lot of money and with Dad in the nursing home low cost would help).
Heck, before anyone suggests it - once I have a new job, I might just get her one myself!
