One of the rumors was that Paul McCartney and Ringo Starr would appear. Another is the posting of a picture supposedly showing the cover of Sargent Pepper's Lonely Hearts Club Band on the suspected touch-screen iPod. These led to the speculation that in addition to the new products, Apple might be offering Beatles' music through iTunes.
The article then went on to point out that over the years Apple Corps (a.k.a. Apple Records) has sued Apple Computer over the use of the name "Apple" two or three times, implying that it was this dispute over the similar corporate names that has led to Beatles' music being unavailable through iTuens.
For a year or so I've been somewhat frustrated by the inability to purchase Beatles' albums through iTunes (which is easier than buying and ripping CDs sometimes), and have wondered why they weren't available even though many other Capitol Records releases were. It never occurred to me that it would be because Apple Corps was miffed at Apple Computer for a perceived (and not necessarily nonexistent) infringement of the company name.
