Apple expanded its retail presence yesterday, right into the guts of your computer, in a move variously hailed as "revolutionary" (Wininformant), "unique" (The New York Times) and "we're impressed" (Forbes).

Only the FT seemed to strike a more realistic note: "Apple music service plays by industry rules," and only today do the bugnotes begin to appear.

Alongside 'Rip, Mix and Burn' are the following warnings:

For example, Purchased Music Does Not Play [Apple KnowledgeBase article 93035] and About Authorization and Deauthorization [KB article 93014]... "You should deauthorize your computer before you sell or give it away"... and How to Backup Purchased Songs [KB article 93033], which warns us:

"If your hard disk becomes damaged or you lose any of the music you've purchased, you'll have to reimport all your songs and buy any purchased music again to rebuild your library."

And remember:

"Initializing the drive will not deauthorize the computer. If you will be initializing the drive, deauthorize the computer first, then initialize the drive."

Huh? Well, it's not like we didn't... warn you.
