"Even if you are ready to pledge a lifetime commitment to the iPod as your only brand of portable music player or to the iPhone as your only cellphone once it is released, you may find that FairPlay copy protection will, sooner or later, cause you grief. You are always going to have to buy Apple stuff. Forever and ever. Because your iTunes will not play on anyone else’s hardware. Unlike Apple, Microsoft has been willing to license its copy-protection software to third-party hardware vendors. But copy protection is copy protection: a headache only for the law-abiding. Microsoft used to promote its PlaysForSure copy-protection standard, but there must have been some difficulty with the “for sure” because the company has dropped it in favor of an entirely new copy-protection standard for its new Zune player, which, incidentally, is incompatible with the old one."
