Apple dictates to you how you can use their product before you buy it.
And once I buy it, Apple's rights to the product cease. As long as I do not violate Apple's intellectual property rights by making illegal copies of Mac OSX, Apple should not be allowed to dictate to me how to use my copy of the product.
Which is the main reason I own no Apple Products, my wife and daughter have an IPOD each and loved them right up to the point when they wanted to transfer their music libraries to new Computers.
I just smiled knowingly and caressed my no-name MP3 player that looks exactly like an IPOD and allows me to copy my music library to any computer I hook it to in two easy steps.
