From the EFF’s web site:
Right now, under the Supreme Court’s ruling in Sony v. Universal (the Betamax VCR case), devices like the iPod and CD burners are 100% legal — not because they aren’t sometimes used for infringement, but because they also have legitimate uses. The Court in Sony called these “substantial non-infringing uses.” This has been the rule in the technology sector for the last 20 years. Billions of dollars and thousands of jobs have depended on it. Industries have blossomed under it. But the Induce Act would end that era of innovation. Don’t let this happen on your watch – tell your Senators to fight the Induce Act!
