Having two options is nicer than just one, but as Peter points out Netsurf is here and still improving so why the need for Oregano3?
I can't believe that O3 is going to be more capable than Firefox in any area except maybe Flash.
We still don't know how much O3 is going to cost but I'll bet my left nut it won't be less than the 25 or even 50 pounds Peter is asking for Firefox.
How up to date will O3 be kept? How often will it be updated (I guess I could ask that about Firefox for RISC OS too but I'd guess it'ed be in line with the Linux version).
As for style guide compliance I think Firefox will basically be a Linux browser running inside a RISC OS window. That is it'll have RISC OS scrollbars and close button etc but thats all.
Having said that, Oregano2 wasn't much better in that respect either. Is O3?
I do wonder how fast either of these browsers will be compared to current offerings of Netsurf, Oregano2 and WXL?
