I wonder how this compares to beaTunes? BeaTunes does this, and more, and is Windows and Mac compatable. Plus it is only $20 instead of $25. I think, before anybody bought tangerine, they should at least check out beaTunes. www.beatunes.com.
You forgot one other factor where switching browsers is easier than switching platforms. I still use IE (on my PC) and Safari on my Mac. Most people are dealing with one computer at a time. One dies and they buy a new one. They would be ditching their Windows box with no fall back. If you don't like Safari, you ask for a refund and switch back to IE. But switching back to the PC might mean a few years. It is a huge commitment. With divorce rates the way they are in this country, why would we expect commitment to a computer platform?
