3D and USB If you have to choose one: My first thought was that if I were Parallels, 3D would be far and away priority one. 3D of course gets you the gamers. But aren't the most serious gamers going to stay with the PC anyways. Most of them are avid, hard-core modders, something the Mac platform does not lend itself to. No 3D in Parallels is one of the reasons I'm holding off getting a MacBook Pro. (I'm using it on the Mini.) But I believe lack of USB 2.0 is more likely to hold back corporate/perfrofessional purchases of Parallels. IT reviewing/recommending/purchasing is mostly what I get paid for. Without USB 2.0, I can only recommend Parallels with reservation.
