Shows linux at 4.2% MacOS at 6.8%
Doesn't mean that linux is at 4.2% or MacOS at 6.8% however, it is an indication that linux customers shouldn't be ignored. Especially in the case that the number of products sold make 1% or 2% a significant amount of profit.
Also - linux users are typically enthusiasts. While it's true that a lot of us lack social skills 😉 we do usually have a bit of a reputation for 'knowing about computers and stuff' and we are often asked for advice.
I've got a 5th Gen also. I use windows purely for testing sites I build. Now I have to use it for transferring songs as well. As soon as I work out a way around this I will be back to using linux to transfer the songs.
PS: I don't pirate, if I must I'll buy mp3s from bigpond music store (I'm Australian).
Good luck all!
