1. FireWire, better IDE (less bugs). Not sure if digital-audio
I can add firewire on a PCI-card so there is no big deal. But you say Pegasos has "better" IDE since it has "less bugs". Can you please tell us what kind of IDE-bugs the A1 will have? Also, since I am a hifi-guy I will, if I want to use the computer for music stuff, add a nice soundcard and not use crappy onboard stuff.
2. PPCBoot is/was intended for embedeed-devices, not for desktops.
And this means that it cant be better? I thought you where smarter...
BTW, I will never buy a mobo that hasnt been out to the masses more than 1 month (or less since the betatesters are not public) which is only bugtested using one specific hardware setup. :-P
