I have to say that after what I have seen /read I probably won't be able to sleep well tonight. Steve at Carrypad.com has stripped down up to the bones the i7210! Please, please, do not do this at home unless you are as mad as Steve is.
Believe it or not the above picture is Steve's eo i7210. The good news is that this poor baby survived the whole adventure and Steve found that this UMPC has two stereo MIC with noise reduction; the same technology used in the Samsung Q1. Another good news is that apparently the Ethernet chip used in this UMPC supports 1Gbps and no 100 mbps as it's advertised!
