Dragon Naturally Speaking Medical on Mac systems?

I am hoping that some of the experts that watch these boards can give me some suggestions. I am a busy family doctor and my medical group has purchased the new Dragon Naturally Speaking Medical (version 10) to begin using for our medical dictation. It is a Windows based app, which is not a problem for most of my Windows/PC based partners, but I am a devoted Mac user and really would like to figure out a way to run this on my existing 1.5 year old Intel Core 2 Duo MacBook Pro, or perhaps a new iMac that I could dedicate to my office. We run a few other applications that are PC only as well. I know that I could do this with Bootcamp, but would like to continue to have iCal and e-mail up and running throughout the day. I don't know if Parallels is good for this? I don't know if the Dragon version 10 software and microphone will run well in an emulation enviroment? I guess I want it all... I hate to spend alot on new hardware, but my MBP is already pretty full of data (ie. I don't know if I have enough hard drive space for a bootcamp partition). Thanks for any suggestions...
