Has anyone considered that Apple's "Rip Mix Burn" campaign clearly turns the iMac into a qualifying "digital audio recording device" under the AHRA? There is no "computer" exemption in the act, only one for data storage media. If by "no computer exemption in the act", you mean that there's no computer exemption in the AHRA, I think you need to look at the actual text of the AHRA a little more closely.
