Stewart (sorry I didn't note your name in your sig earlier),
Whatever it is you decide to do, I wish you luck. Again, in general don't buy too much into too many "universal" comments. All computer systems have their issues. I"m not saying anything one way or the other, but it would not be wise to consider switching to a mac being an absolute up-front-only cost. You never know what might happen down the road, what might break, what a company may or may not repair under warranty in a proper manner, etc.
