Summary: I have had both the Roku and now the Apple TV. I like the Apple TV because I am an avid Apple user and especially enjoy the ESPN option. It truly is the perfect option if you are looking to not spend money on cable. The only con I have to this product is there is an additional cord you have to purchase from Apple that I wasn't aware of, so I had to go buy that cord to finish the installation process.
Summary: I put off buying this for a year or so after I tried it at a friend's house. I finally caved after an evening of using Direct TV's rather painful interface to watch YouTube and other videos. Apple TV is great! It's much easier than navigating to Netflix on my Wii. The history makes YouTube faster to navigate. Watching iTunes content from my computer means I'm watching old favorites I haven't seen in ages. And I even use the mirroring to watch other web videos.
Pros: Attractive Design, Easy Content Access, Fast Setup, Simple Controls
Summary: This unit is a great accessory for any TV that has an HDMI input. I have an iPad as well and this allows you to push content from the iPad right onto the TV screen. The interface is very easy to use as well. It only took about 5 minutes to set up.
