On the down side you have to boot into the BIOS to change the HD boot order to get to the other drive, a extra step. Could get tiresome if you do it frequently. I tend to stay in Linux so its not a problem. Having separate drives for each OS is a option.
Dual booting shouldnt present any problems. If your machine is purchased this way there should be no problems. If you plan on adding Linux to a drive that has Windows installed already then I would read some guides/tutorials first before proceeding. Also visit the distro's forum for information. Linux installations have really gotten much more 'user friendly' than they use to be.
