Count me in as well. I originally used Parallels with a Bootcamp partition but moved to a VM file because having to shutdown Windows everytime was too much of a pain. I very rarely needed to boot into Bootcamp but it'd still be nice to have the option to. It looks like you guys at Parallels have spent a lot of effort implementing Bootcamp partition support but that ultimately users do not use this feature because it's too much of a pain not being able to suspend the VM when using a bootcamp partition.
I'm a grown up boy and can remember to shut down Windows first in Parallels if I ever need to boot natively into Windows via Bootcamp.
