There are tomes on the web about studios wanting to keep the pace of innovation under control, patents and more. So the answer is simple. Why buy if this doesn't do what you want?

I can't believe samsung didn't put the smart view mirror app on the samsung tab 3 this is rediculous how you can mirror photos but not videos. This tablet was bought for my birthday to go with my 50" led 3d smart samsung tv, i can download movies on my tablet but can't mirror to my tv, i really hope samsung will sort this problem as this is really disapointing
