Okay, I bet a million people have asked this question already. Correction: I have seen a million people ask this. But none of the answers seem to address the needs I want... I currently use VMware Fusion on a MacBook (Late 2009) and there is one thing I can complain about. It's slooooooooow. So slow in fact that in order for me to not throw the computer across the room, I have to actually turn off AirPort to speed it up. I hate doing this, and I'm wondering if VirtualBox is any faster, and if it's worth it risking being unable to go back to VMware if I switch. So, the specific things I need: -Speed, just speed in general. -Ability to use vmx images -Speed when using music editor/video editor/sound editor programs, in the Virtual PC (This is the most aggravating one) -Game support...at least a little...maybe? -Drag/drop file transfer -Integration between Mac and PC sections -Ability to back up (like VMware's snapshot function). Now, I've already bought VMware two years ago, so the money's not a problem. I'm perfectly willing to consider my spent $80 a waste if it turns out VirtualBox is better. So...any thoughts?
