I have a Mac at work and hate it (I tried other OS's such as Linux w/ varieties of distros) but I always enjoyed using windows. Vista is a little off the hook but we will catch up to it and I am sure it will be good one day. ;) The PCs are ridiculously at a cheap price today. I would say, go Windows all the way. I know there are thousands of viruses and spy-wares for windows but who cares, the leader is always the prime target (PC)...
