Just to be clear, the blue display is not the only difference between the AVM20 and AVM30. Here are the ones that I know of:
4 component ins and 2 component outs (up from 2 and 1)
Faster processor (more than double the clock speed)
Double the memory on the motherboard
Blue readout and blue/red LEDs
Finer grain on the front panel
Optional rack mount
Also, the PLIIx upgrade is not yet available for the AVM20, but is for the AVM30. I'm not sure about the status of that. The component out difference was the dealbreaker for me when deciding between the two. That and the fact that the MSRP was actually a bit lower for the AVM30 made my choice easy.
