> I asked it when apple announced 64 bit support for the iPhone, and I'll ask it again now: what is the point in 64 bit cpus in devices that will be deprecated and replaced before we get around to having more than 32 bits worth of addressable ram in these devices? I imagine the additional cpu registers (general purpose and floating point) are handy for crypto and encoder/decoder stuff.
