iTunes 7 came under fire for several bugs and poor performance. These issues have largely since been addressed with further updates.
We made the somewhat surprising discovery in a routine poke around of the company's in-store Macs earlier today.
When we undocked and then re-docked the attached iPod, the machines moaned that they required iTunes 7, and didn't have it installed.
The oversight puts the company in a rather amusing situation, especially since an on-screen message asks you to install iTunes 7 from the supplied CD. Cost-cutting Apple no longer supplies iTunes on a CD; you have to download it.
