I'd like to see the ACPI support improved, so that I can take a backup made of a real PC, and do a "bare metal" restore into Parallels. Right now I can do the restore, but the Windows driver tree gets smashed due to different ACPI profiles. The only way to fix it is via a very time-consuming and problem-laden repair install, and reinstall of all service packs and patches, or by deleting large chunks of registry by hand.
