Netsurf is the most used browser on my RISC OS system. I think the team should be congratulated for getting this far - a really good achievement and I'm sure the continued development and interest has kept a fair few people interested in the platform. As far as JS support goes, I agree with alex a bit - having a Linux machine also means that sites which are not compatible with Netsurf I can still view, however is JS was supported then it would be slightly more convenient
One question that I wonder from reading the article is just how much foundation work would need to be carried out before JS support could even be started. If the browser requires a new engine then surely thats a hell of a lot of coding needed? What sort of time frame is required and if a new engine is needed then wouldnt that mean a duplication of much of the work already carried out (albeit it in a different direction)?
