KH: I don't know for sure, but I'd have to assume that it could since it's capable of charging from the USB port.

Lorenzo: Processor development for handhelds is different from processor development for desktops and laptops. In the later, Moore's "Law" still holds that the processing speed doubles in about 18 months. Those processors are larger and have humongous heat sinks mounted on top of them to handle the heat dissapation issue. Handhelds can tolerate none of the size, power, and heat dissapation requirements of desktops and laptops. It's true that handheld processors haven't increased in clock speed in almost four years. That sounds odd at first until you consider that the vast majority of the development has gone into smartphones, the majority of which don't run at anywhere near the maximum speed available for their processors. (Development is more centered around lower power requirements and better efficiency of operation.)

With that in mind, it still might seem odd, but at least within reason that the processors in the 200 series and 4700 series run at the same speed. One should expect better battery life and efficiency out of the 200 though.
