Anybody got one yet? Does it work? Just got one Friday(3/3/0) and installed it in a rev d iMac. works as a reader but MacCDR 4.0 will not open...waiting for input from TW tech assist(actually the engineering manager) for a solution to that...mechanically everything went well, a Sony mechanism and a perfect fit...barring major bugs(none so far i think), this looks like a BEAUTIFUL solution to iMac BackUp woes
