I bought an Apple TV a while back. It is just what you would expect from Apple. Simple. A power cord and an HDMI cable (Well and an ethernet port however it is wireless) It was easy to set up and connected right up. Apple Air Play is the best. You can simply touch a button on the iPad and it displays whatever you have on the iPad screen (Via Wireless) on the TV screen along with audio.
This along with access to your iTunes, Netflix, put your pictures on the TV and much more. Pretty good value for less than $100.
