can I put a pop on a mac that has windows as well? if so, do I need 2 pops.. or just one.. does this matter. I am going to partition the mac as I have needs for windows apps and want to move to mac/safari... also I want to get android.. because I don't think ATT is a good cell phone provider.. so will be sync from my old treo 650 to windows and then use the android.. will this all work seamlessly... changing over is a drag.. but I really want to do this.
