Apple is now selling an entire Beatles discography on iTunes.  Rolling Stone Magazine says:

At 10 a.m. ET, the group's 13 original albums, the two-volume Past Masters compilation, the 1962-66 and 1967-70 collections became available from the iTunes' Store as albums or individual songs. Also available is a digital boxed set featuring a video recording of the group's entire first U.S. concert in 1964 — and that concert can be streamed for free from the iTunes site through the end of this year.
