Officially, no comment on IE7. FF2 and I have a love/hate relationship, and I'm not even going to touch FF3.

I just miss two things: one, the proper handling of the d-pad. I liked being able to browse pages lynx/links/elinks/you get the idea-style: jump from link to link where available, and scroll if there are no links. On my MicroB with pages with no links, the d-pad does nothing on short presses. Along these lines, I also find a lot of pages where some links can't be hit with the d-pad --- no combination of presses reaches an element --- and some pages with lists of items where one item can only be accessed going down, or going up. Left and Right / Up and Down should always, always switch between the same two elements...

I also notice I can have no more than three windows open. Four almost inevitably causes a crash, three bogs down the system, two is ok only if I'm not running anything else. Even with one window open, if I'm running Skype and a notepad, I'm pushing the limit of what I'd call acceptable response time. Opera handled five or more without complaint.

Yes, JS-heavy sites work when they didn't before, likewise Flash 9-sites: however, I find JS and Flash performance so slow that I browse with it off. No real gain there.

Adblock causes dramatic startup slowdowns for me, takes multiple seconds per click when being configured, and adds a second or two to each pageload. I guess I don't use ad-heavy sites?

I didn't think of playing with the about:config settings, good call, let's see if they help as much as they did with FF 1.5

Talk about damning with faint praise.

All this said, I'm still the envy of my Windows Mobile-toting friends, and even some of the iPhone fans are blown away by flash working, even if it's slow.
