So I'm thinking about buying Win 7 to run on my MacBook. My question is, should i go with the OEM or Full version. I've heard that the only differences is you don't get Microsoft support with OEM, and while in the full version, you have the option whether to install 32-bit or 64-bit version, on the OEM you have to buy either 64 or 32-bit version. Is that the only differences between them? In that case, i will go for the OEM, since it's alot cheaper.
