I think that a mobo with AGPx2, no FireWire, USB 1.1 etc. simply has to at least try and compete with the latest PC mobo's offering AGPx8, 2 x LAN, RAID, USB 2.0 and the rest. Especially within the A1 price range.
it is not in direct competition, so who cares??
amigaone will probably mainly be aimed at developers anyway
