One of the things I like the least about all of these boxes (Apple TV, Xbox, Roku) is the need to type in a password in front of everyone in the room using a joystick or the arrows. The whole concept of a keyboard on a screen that's used by only 4 buttons reminds me of the parody onion article when they discussed removing the keyboard on the MacBook in favor of a click wheel. It doesn't make sense.
The Roku devices support a mobile app that allows for keyboard input on your phone in most situations.
