I may be ready to buy my first Macintosh today. Going full-tilt with a Mac Pro 2.66 Dual Core and 2GB ram. I own a crapload of Windows programs. In fact, my entire business runs with Windows programs so essentially, I'll be buying a Mac to run Windows. This is fine as I am sure I'll slowly migrate over to Macintosh for some functions. I do not want to use boot camp. My entire Mac existence will rely upon Parallels. I have a few questions I hope that all of you will answer though I am sure it has all been answered countless times before.... 1. Is there a considerable slowdown either to the outside Mac or inside Windows environment using Parallels? 2. Can I keep both environments (Mac and Parallels) running at the same time and switch between both? In other words, as a far out example, can I have my webcam outputting in MAC but use my Windows based Instant messenger in Parallels at the same time? 3. Will Parallels run FULL SCREEN so it actually looks like I am on a PC computer? 4. All my business is run through Microsoft Office. I want to keep my 2007 Windows version as I paid a premium to buy it. Can I effortlessly continue to run Windows Office under 2007 including using CONTACT for email and synching with my PDA? 5. When you hook up a PDA or other device through USB that you want to use with PARALLELS, does it get recognized by the Mac OS to run on MAC or by Parallels? Some I want recognized by Parallels, some by Mac. Is there always an easy way to differentiate between the two? 6. Great Question: Running Windows in Parallels under Mac.....do you get software conflicts and blue screen crashes associated with the problems you get on a PC -or- does the Mac environment help stabilize things? 7. Will Parallels run Vista? 8. Am I better off buying Parallels on CD with my Mac Pro or go to the Parallels website and download from them? I think downloading may give me the latest version that may be compatible with Vista. I know I asked a lot of questions. This is a huge purchase decision based on the fact that I am new to this OS and I am a power Windows user who needs to *slowly* migrate to Mac. Thanks in advance for your assistance.
