How does VirtualBox compare to Virtual PC 2007 in terms of resource use, features, etc? Are you familiar with both?

I've been using VPC 2007 for a while, it's a simple setup, XP SP3 as the guest, just to test software, screw with the OS - nothing groundbreaking. Win XP works adequately with 512MB of RAM. I began to look into VirtualBox but got distracted by something else. If I finally get off my butt and upgrade this old PC with parts I've had for some time, I would like to try VirtualBox, with a slightly faster CPU, 2GB of RAM (1GB for guest OS), and a faster / larger disk drive, but, only if it really is superior to VPC 2007 - thoughts?

The biggest reason I didn't like VirtualBox was there's no drag and drop. It's been requested for a loooooong time and they still don't have it. Aside from that it's a good app.
