I have an ASP.NET MVC 4 app that I would like to run on a Mac machine. I would hate to run a full blown Windows virtual machine when all I really need is IIS7 to run the MVC
I use Parallels, and although their software was poor a few years back, it's now lightyears ahead of VMWare in stability and performance. Parallels Desktop 7 for mac is awesome.
My only computer is a MBP, yet I develop software for IIS. I run Parallels in Coherence mode, and I essentially have VisualStudio as just another mac app. And since I'm only running one app in the VM, it's way more stable than a normal PC install. I actually haven't rebooted it in 2 months so far!
Only caveat - you want to dedicate 2-4GB of ram to the VM to prevent paging, so you should try to get more than 8GB if you're a polyglot developer. Having multiple IDEs on multiple OSes can be heavy, and when you add the memory-hogging yet blazingly fast Chrome to the mix, you'll hit that ram limit often...
