The design of the small black brick called AppleTV is excellent. You can easily hide it below or behind the TV. I love the fact that you don't need a line of sight connection to it. The remote, however, it a complete fail. It's just too small, easily falling between cushions on the sofa. Then there's the fact that you can't tell which side is up when you pick it up in the dark. The rechargeable battery is excellent, though.
Apple, take a lesson from your own keyboards. Keyboards are designed to fit human hands, and so should remote controls.
[doublepost=1470406418][/doublepost]The grid of app icons as an interface might look pretty for new users, but it really breaks down fast as a user interface. It's so slow to navigate the screen that you are virtually assured that you'll never watch the channels at bottom of the list.
The best current TV interface for me is by TiVo.
Simple scrollable list of channels on the left plus list of what's up next on the right. It gives much more information than the DirecTV or standard cable box style of channel grids.
If Apple insists on keeping the grid of icons, I'd like to see these enhancements:
Option to arrange the icons by name, by recently added, by most used, etc.
Option to change icon sizes
Option to pin selected icons at the top
Make the grid of icons loop after you get to the bottom.
That would be a start.
