There are also lots of other improvements from the alpha feature list. I used Fennec to check out some of my favorite sites (including my ZDNet blogs) and found that it still seemed to be a bit sluggish loading some heavy ad-laden pages, but it did load the full version of them too. It was actually quite fast with Google Reader, which is where I live most of the time. I just may be using my N810 more and more for browsing on the go now.
It took me a while to figure out how to get into full screen mode since the upper menu (and associated button) doesn't seem to do anything. From their tips & tricks section, to use the full screen for browsing, click the button on the left hand side on top of the device (to the left of the -/+ buttons).
If you don't have a Nokia N810 to try it out on and want to see how it may eventually work on your S60 or Windows Mobile device you can install it on your Windows, Mac, or Linux computer and try it for yourself.
