16800 vs 16850

I am comparing the 16800 and the 16850 logic analyzers. It seems the 16850 is much better value for the money. The state and timing speed and the memory depth of the 16850 is much higher for a similar price. So I am a little confused. Is this the only difference between these two units?

In the 16850 datasheet, it talks about a "Minimum state clock frequency (typ) 1", which is stated to be 12.5 MHz. This doesn't make any sense to me. The state clock doesn't have to be a periodic signal, it can happen at anytime. So what is this minimum state clock frequency?

In other words, given the superior specs of the 16850, why should I even consider getting the 16800? Is the 16850 limited to timing analysis at very high clock rates and can't work at low frequencies? Hopefully someone can clarify this...
