That book sounds really interesting. Shame about the crazy price (but I suppose they only expected a handful of readers...).
Curiously, if you connect a microSD card to an Arduino, there's more compute power in the card than the Arduino (typically an ARM micro controller or something of similar complexity to handle all the protocols and wear leveling that microSD cards support).
