A user of Apple's iTunes music service is suing the firm saying it is unfair he can only use an iPod to play songs. He says Apple is breaking anti-competition laws in refusing to let other music players work with the site. Apple, which opened its online store in 2003 after launching the iPod in 2001, uses technology to ensure each song bought only plays on the iPod.
I believe that Apple would allow other manufactures to use the encoding if they were buy a licence. I could be wrong.
But what I do is burn a CD with the songs I purchase from itunes and then rip the CD to mp3 files and then put them on my non Ipod player.
