> Compared to the model B: 70% of the price, 0 ethernet, 1 usb†, > 256M RAM, same CPU, 1/3 of the power draw, a little thinner. I didn't realise that the Model A's power-use was a third of the Model B. While that might not make a huge difference for most people, it'll be a definite benefit to those using them in `always on' situations where connectivity isn't so important. I'm a little surprised that an addition 256MB of RAM, another USB port, and an ethernet port can triple the power use though...

That's because you're used to desktops, where Intel/AMD CPUs and screens take the vast majority of power. But the RasPi has no screen, and the CPU is a small, slow ARM. It's not surprising that it takes so little power compared to peripherals. Of note, there are low frequency (kilohz to low mhz range) 32-bit arms that can runs for months to years on an AA battery; They're starting to become the microcontroller of choice.
