I have to say that I'm a bit disillusioned by that glitch over ethernet jacks. For anybody who hasn't chased down the gory details, a twisted-pair ethernet interface requires coupling transformers. The Pi interface uses jacks which have the transformers built in, but somebody substituted 'plain' jacks instead, so they didn't work ( and couldn't work). What worries me is that this suggests they simply did not properly test ANY of these boards, not even a tiny sample, they just assumed that since they'd specified them correctly, they MUST work.
For £16 you cannot expect every single specimen to be exhaustively tested, but I'd have thought the first handful off the line would still get tested, and thereafter some small statistical sample being tested. But the evidence suggests that didn't happen. Or maybe they tested them, but the tests were inadequately specified... testing external interfaces & connectors ought to be pretty fundamental to any production testing, though.
I'm still interested, and still enthusiastic, but I have to say my enthusiasm's a little dented. I'll watch with interest...
edit, corrected 'STP' to 'twisted-pair'
