Oh really?
"This would mirror the way Apple uses iTunes only with the iPhone, iPod, and iPod touch."
If you mean that the Zune will suddenly resemble something other than a dodo, you're completely wrong. I've only met one person who had a zune and when I said "I've never seen one of those before" he said "Well, I'm selling it on eBay and if I get a buyer I'm buying an iPod mini".
Shutting out users of other players isn't doing MS any favours when their own player is a pile of poo.
In contrast, Apple have a VERY high profile player that doesn't seem to be going away any time soon AND you can download tracks on Winblows systems...
So when you said "mirror the way Apple...", you actually meant "be an inferior and completely different solution to the way Apple..."
