The pint-sized player, which costs $100, slips into an MHL (Mobile High-definition Link) slot on the TV, which looks like a standard HDMI input. The Roku Streaming Stick, which supports 1080p video and multi-channel sound, has built-in Wi-Fi and doesn't require a power cord, so there's nothing else to attach.
