Just a FYI for all of you out there wanting to buy Parallels workstation for Windows and Linux. Vista is not fully supported as a host. I was getting a network driver error on vista ultimate and the software wouldn't even install. I payed for phone support and here is what the guy who barely spoke english ( I love the quote on the purchase support page that says "At this moment we can provide you with phone support in English only.", would be nice if their support people actually spoke the english they were supporting), anyway, he said: "Some versions of vista are not supported and wont be until the next release of the software." I found that very interesting since the front page of this software has claimed full vista support since November 22nd. I am getting a full refund for the purchase price of the software and the support call. I love this software, but their very much putting all their efforts into their mac side, because their windows side, while the fastest visualization software I have found, is very sad in comparison to the mac version in form of features and support.
