I've been a software developer for many years. I've brought a copyrighted product to market and have worked with trademark and copyright lawyers extensively, both external firms and internal legal departments.

Software owners are permitted to make a backup copy of software they own for personal use, contrary statements in the EULA not withstanding. There's legal precedent. Non copy provisions, in this circumstance, are unenforceable and irrelevant.

Regarding use on a second computer, I'll concede that the EULA sets that policy, however, you wont find me flaming anyone for this practice, and you'll never see a vendor pursue a customer for a secondary "laptop" installation, that's not their intent.
