OSNews has a great writeup of the open source browser for the Series60 platform that Nokia has been working on. I stand by my assertion that I would like to see more code to go along with the talk, but there are some interesting points in there. Such as the team choosing the KHTML codebase over Mozilla because of readability of the code in addition to the size requirements.
The minimap interface sounds interesting, although I’m curious to see how it works out in practice. It’s one of those things that I can see benefits and disadvantages for, and I’ll have to play with it for a while to see which factors lend the most weight. The availability of a plugin architecture is promising as well. I think the mobile web definitely has a lot of growing to do, and allowing for incremental updates to browser functionality could provide a step in the right direction.
