(Most important question) why is their no safari or web browser on Apple TV ?

This might be better answered in another forum area, this area is for Apple Music questions.

Having said that, I much imagine it was probably a design/usability decision to not build Safari for tvOS. For most people the experience of browsing the web on a TV is probably not a great experience. You'd have to have a keyboard paired to your Apple TV and the lower quality resolution of most TV screens probably doesn't make smaller text look to great either. Just a guess though. If you've got an iOS device or a Mac, you can AirPlay/Mirror that device's screen via Apple TV to your TV and essentially browse the web using Safari.

Exactly, and it's much easier to use the browser on iPad or iPhone and AirPlay the video to ATV. So an ATV browser would be both inconvenient and pointless.

browsers work for touch and for keyboard and mouse

otherwise it's a pain,

my xbone has a browser which is a pain so I never use it

when apple don't see a feature as being good for 99% of the users they remove it

Except that u can hold the mic button & TALK TO IT so it would be awesome ... no ?
