LOL i have both. But they both have Windows and OS X. but... the windows PC hardware seems better. the mac is a stock Mac Mini 2010 (aluminum)with a Geforce 320m, and the PC is a lenovo think center with a GeForce 8400GS /512MB. cpu's are pretty much the same in both. The thinkcenter Runs NL2 on windows better than the mac. even though the mac is Newer machine.
