Any suggestions on the cheapest place to get a (legal) copy of Windows 7? I plan on running it using Virtualbox, or maybe Parallels/Fusion if I decide to get one of those as well. From my limited searching so far, this is the best deal I've found ($100 from Amazon with free shipping): http://www.amazon.com/gp/product/B002NGJO4M/ I'm also a little confused (not surprisingly) at how many versions there are out there. I assume the 64-bit home version is fine? I basically just need it to test out website rendering in IE. Recommendations?
