I'm wondering for those who use VM Fusion how much time you spend in Windows? For the next few months I'm working on Projects that will require me to use Windows and I won't be over the OS X world much ... in that case I'm wondering if I should of went the Bootcamp route instead? Or, are there people using VM Fusion and spending 80% or more of their time in Windows? My concern is if I'll burn up battery time faster running two OS's at once as opposed to running Windows only via Bootcamp. And, would I save a lot of system resources with Bootcamp running only one OS at a time ? Thanks.
