I love messing around in VMWare and Parallels, and I also love playing around in other OSes in VMs such as the new developer preview in Windows 8. I also refuse to leave the Mac OS platform while doing so (it is nice to be able to three finger swipe between OSes). Should I max out at 16GB of RAM for my MBP? Where do you guys recommend I buy this RAM from? I know that Crucial has a 16GB kit for my MBP for $120.
