Well the OTA update installed, and fortunately I'm not encountering any of the reported problems, except with the stock browser - the exising bookmarks square is gone form the browser - window, but you can still open it by clicking on the star on the upper right of the browser. Also, the pinch zoom in the stock browser seems a bit flakey, but maybe that is just intentional changed behavior.
One difference I seem to notice (or imagine) is in the grid mode on the applications screen - when you swipe to the left or right, there seems to be less of a responsive "floating" quality - it just abruptly moves to the next page of icons. But, again, this may be an intentional modification. It also seems as if the icons are slightly smaller, and it's easier to accidentally hit one when swiping horizontally through the program icons, which is annoying. There are some new program icons added to, which is nice, but the Browser icon has been changed to Internet, which makes it harder to instantly locate.
I don't like the Select icon being added to the top pull-down bar in that that makes the other icons smaller, but I may grow to like that it is now easier to put the phone into silent mode.
So I don't regret doing the upgrade so far.
