As much as I think NetSurf is easily the best browser available on RISC OS, and probably has a lot of potential, I'm not sure that if we only have resources to pursue one browser on RISC OS, that NetSurf should be it.
In the shape of NetSurf we have a browser that has not had any RISC OS work done on it in quite some time. If that changes, and they get a RISC OS maintainer, then we'll still have a browser that is not capable of going on a lot of websites.
Maybe we'd be better off looking at Mozilla Fennec, which is like Firefox but aimed at smaller devices, or maybe Origyn, which is a portable version of WebKit.
