If you have to Windows on a Mac, there are 2 ways I like to go. If it's just for running apps, I use VirtualBox which is free and gets regular communal updates. Haven't had any application not run on VB (yet).

If I need heavy duty I/O (as for PowerSDR and the Flex-5000 line), I'll use Bootcamp from Apple - allows for partitioning of disk for a Windows install, Windows drivers customized for Mac hardware and then boot into Windows. That way I get close to full bandwidth Firewire access when needed.

Was very impressed with MacDoppler, but using a Flex, I run Bootcamp.
