> Why wasn't Intel interested to supply the CPU for the iPod?

Just adding some historical notes, Portalplayer's IC was used in the iPod until 2006ish ( https://en.m.wikipedia.org/wiki/PortalPlayer ), the first iphone used a Samsung ARM chip (https://en.m.wikipedia.org/wiki/IPhone_(1st_generation) ) , and fabless design companies like P.A. Semi and Intrinsity were acquired by Apple in 2008 and 2010, respectively.
