Has anybody peeked at the guts to see what the CPU situation is? I'm definitely liking the very noticeable speed boost!

Same eZ80 CPU @48MHz for non-Python stuff, but new faster serial Flash chip.
So everything within the OS is faster.

Ahh, that would explain it. I remember reading something about the previous model using components that were more suitable for an ARM CPU that could handle wait states more gracefully. In any case, it's a LOT faster than the one I got a few years ago, which is a pleasant surprise.
