I've recently switched to a mac and I love it. It is a good chunk of money, but my husband has had a macbook pro for about five years now and we've had no hardware issues or problems with it at all. My son has an imac desktop and it's been fantastic for him. He can usually destroy a computer fairly quickly, but this one has been durable and resistent to any problems. It is a fair amount of money compared to Dell desktops, but I know you've had some issues with PC's in the past so it might be worth looking into.
