I did the same thing recently, and I've hated it since. 10.7 removed Rosetta, broke "Save As", and annoyified the Save dialog.
But there were just too many pieces of software that wouldn't run, and unpatched security holes didn't seem like a good idea either.
To add insult to injury, Apple doesn't allow you to virtualize non-server versions of 10.6. You can, thankfully, hack VMWare Workstation and keep running your previous machine's image that way, but it's shitty that you have to jump through those hoops. It seems geared specifically towards keeping people from continuing to use their old apps.
