Okay, you might find this to be a little weird, but, I use a Mac and OSX 10.4.11 When I had seen my very expensive, highly customized, literally hand built PC starting to bite the dust, I began saving for the new PC. It was time to start fresh and have a nice clean machine. Eventually, the PC that served me oh not so great over the years and upgrades really started to begin being unstable. I went out looking for something off the shelf this time, rather than having it built to order. You know, something with a warranty and service, etc., so that I would not have to spend so much time and money.
What I saw and read about Vista really bugged me. Especially the additional cost and the versions I would need. I went and tested a lot of machines, and wasn't impressed, besides, I would still need XP in order to run acad and LDD. I was bitching about the aspects of Vista, and the general crappiness I thought it was when someone suggested I shut the &*#$ up and go look at a Mac.
So, I did. I went to the Apple store and asked "but I still need to run windows?" and the kid whipped up Parallels and a window opened with XP running in it. Afterwards I went online and researched the performance of acad and LDD under a VM like Parallels, and found no one really had any problems. So, I did it. I now run acad under XP in the VM, and everything else I do using the Mac side. I keep the VM and XP disconnected from the network, so there is no need for any antivirus software or firewall, etc. I don't need it if I'm not hooked up to the internet. So far, I have had no problems with performance at all. And I have never had a problem with the Mac, no crashes, meltdowns, anything.
Mind you, this is my home machine. At work, they have me on a networked Dell and it is crap. It crashes, becomes unstable, freezes, etc everyday, multiple times each day. Granted, home is an ideal situation, there is no monitoring software running, no av, no print monitor, it makes for a very clean system. At work they have so much bullcrap loaded and running on the machines it sucks up all the systems resources. But there's nothing I can do about that, that is what work and IT Guy want.
