Because it costs $99
If it ran full fledged iOS, I'd say it would be around $500.
I never said full fledged iOS. I said the same icons, functions in those icons etc.
In other words, take iOS and cut out everything not needed by a TV and use the rest. With the same UI. When you click music on an iPad you get your music NOT the store as you do on the Apple TV. That is dumb.
As is making folks to go 'computers' on the Apple TV or 'shared' on the iPad etc for home sharing stuff. It should be on the same list. Everything you have access to together, in order of local, shared on your local net then 'in the cloud'. All streaming or downloaded per your default or tap. If you default to streaming then tapping the name or random play does that so long as you are Internet connected (with you having the power to say any connection or wifi only). If you want to download it you tap the download button etc.
