Thanks for the article.
However, I dislike the reasons for why Chromium and Midori were not included, they could have been tested anyway with a note that they crash "frequently". Though in my experience that is not even the case.
In fact, Chromium is not too bad since it is pretty fast and has a great auto-completing URL bar (awesome on the Pandora as typing with two fingers is slow).
The lack of addons is sad, but for general usage probably not necessary anyway. I personally don't mind that it's a fullscreen "ChromeOS" since I want to browse in fullscreen on the small screen of the Pandora anyway.
Midori also runs pretty fast and it had kinetic in-website scrolling once (aka you could just click and drag inside a website to scroll, could be done with a finger), which for some reason got removed in an update, then added again, then removed again, then...
You are probably right that these browsers have been superseded by current ones, but I think they have some unique features that are worth mentioning. (Since it comes down to personal preference anyway).
For the record, here is an "ultimate" comparison kloplop321 did for PandoraPress quite some time ago, it includes a bunch of obscure browsers which are still floating around somewhere. It might be interesting to compare and see how browsers evolved over time.
Sadly the textual article is gone, so here is only the videos:

(It also shows how absurd FireFox's version numbering has become, since it still was version 4 back then...)
