Yeah I think that right now 600-800mhz is really enough for most people granted the efficiency of current processors. 500mhz might feel sluggish at times.
I would gladly replace my phone for a device with a new gen 600mhz that would drain less energy though, even though in theory it would look like a very stupid thing to do. I've never had any issues with performance, I don't need more. However I'd really love longer battery life.
That's why I'm all for ultra low voltage processors and new AMOLED displays. After all it's mostly because of processors and displays (and gps/wifi/gprs modules) that smartphones are known for rather short battery life, despite packing 1500mAh beasts. Fortunately with Android everything changes quickly.
