So I'm maybe missing something, but Other Products 2014 didn't include Beats headphones sales, right? Because the acquisition didn't happen until Aug 1, 2014?
And Other Products 2015 explicitly does include Beats Electronics.
And wikipedia (https://en.wikipedia.org/wiki/Beats_Electronics) says that Beats revenue in 2013 was $1.5 billion.
If all that is right -- and it may not be -- then that implies that Beats + Apple Watch < $1b revenue, which would indicate that something is very wrong. Indeed, it would imply that something is SO wrong that I doubt I have the facts above correct.
EDIT: Duh, thanks thedaveoflife, obviously the $1.5b for 2013 Beats is an annual number, not a quarterly one. And of course the iPod numbers are presumably shrinking. That explains it.
