Windows 7 with MS office, project and visio will take less than 30Gb. BUT both Fusion (which I own and love) and Pralllels like a lot, repeat A LOT of RAM for the virtual machine to run smoothly. Typically I set aside 4 GB of RAM for just the Windows environment, so you need to have at least 8 GB of RAM on the macbook pro.
Have fun!
Yeah, the storage requirements are basically the same as if the VM was just a standalone install. In fact, my VM I've been running for several months was a ported over Windows 7 install from my previous HP notebook.
I just recently upgraded my Parallels to 7 (had to with my upgrade to ML) and it's faster than 6 (or using ML as a host OS is faster ... or both
🙂 ), I should be in for the free (or "free") PD8 update.
When my machine had 8GB, I did a 4/4 split, now with 16GB I'm doing a little more in the Winders© VM, ~6GB (sometimes I even have a Linux VM running too if I'm moving between projects at the same time).
One thing I always suggest: go OSX native where you can. i.e., for Mail, Browser, iTunes, MS Office, etc., if the OSX is an option (as in, price and feature set).
I run "windows only" apps in windows and nothing more.
