One weak spot of the MicroB browser is the very slow performance of javascript on sites that rely heavily on it, like google maps. Recent builds of of the gecko rendering engine MicroB uses have significantly optimized javascript efficiency, and it looks like the next version of firefox is going to push performance almost to the level of native code, which might be enough to make javascript heavy sites usable on the tablet I don't know if this technology is x86-specific, though. Any idea if or when we're going to see this implemented in MicroB or even Fennec?
