I just returned my new iMac and 'm waiting for a replacement. I know USB 3.0 is coming out and would like to know if it will be faster than Firewire 800? It 's confirmed some of computer providers will be releasing their products with USB 3.0 ports on this month, January. like Lenovo Thinkpad W510 I'm thinking of returning my iMac for the refund and wait til new iMac comes with USB 3.0 ports (if it is a lot faster than firewire 800) and of course wait til Apple has eliminated all current problems for this iMac. Do you think I should wait until then? or just keep this current iMac and sell it when the newer one comes out?
