Ray,
Whenever people have asked me if it's worth the extra $$ to buy a Mac or any Apple product, I always point out that Macs/iPhones/iPods etc actually have a "gently used" resell value. I know people who buy a new MacBook and sell their old ones every couple of years and get a decent value back on the used ones; it makes the total cost of ownership much less. I don' think I could pay anyone to take my 3 year old Sony laptop!!
Steve Jobs will be getting some good business from me this year. Will definitely be getting an iPad and will also be updating my iPhone when the new ones come out this summer.
