<p>Get Windows if you need a program not available on a Mac.
Running Windows as a virtual machine on you Mac desktop,
makes for a slower Windows machine, so it depends on what you need it for.</p>
<p>From your original question, I assumed you wanted to run Bootcamp - or was that a question about running Windows on Parallels?</p>
<p>No Bootcamp for me…
I use a tower PC for work, I need programs not available on Mac
Mac laptops, used for web, email etc., no need for windows there.
I use Google Docs extensively, allowing myself access from wherever.</p>
<p>I use bootcamp. Worked like a charm for me. If you have installation/driver issues, there are countless websites (including Apple’s own) to assist you. My friend took hers to a Genius bar at the Apple store, and they just set the whole thing up for her, for free (she’s not technically inclined).</p>
<p>For your original question, here is a guide. Simply download the iso (scroll down to the bottom of the first post) and since you have access to msdnaa then you should have a legal key.
scroll down to the iso method, and then once it’s downloaded, check out the second link for a tutorial on “How to Install Windows 7 on Your Mac Using Boot Camp”</p>
