Summary I bought the Apple TV 2 primarily for Netflix and the interface Apple TV provides. There simply isn't a better interface available, period. After the update brought AirPlay, that put the icing on the cake. For $99, and iOS device compatibility, there isn't anything better. Streaming music to my home theatre from iTunes on my Mac or iOS device is a fantastic feature.
One of the least noted features of the Apple TV is Internet Radio. There are hundreds, if not thousands, of stations available. There are many genres to choose from, and tons of stations for each one. When you find one you like, hold down the button in the center of the directional button to bring up the menu to add to Favorites (the same to remove). It then creates a section for Favorites at the very top of the list of genres in the Radio section. Once you're in a genre with a station playing, you can push forward or back to change to the next or previous station in that genre, just like SEEK on a stereo. With the wealth of stations available, I don't see the argument for Pandora on Apple TV. Pandora seems like too much work. If you want it that bad, just use AirPlay from any iOS device running the app. It works flawlessly. If you have more than one Apple TV and home theatre system (or sound bar), just set them both for the same station and enjoy the music throughout the whole house.
I bought a Roku 2 XS because my bedroom TV didn't have HDMI and I wanted to try out Hulu Plus. Well, it's a joke. You pay $8 a month for a horribly clunky interface that's slow and almost unresponsive AND you have to watch COMMERCIALS! I cancelled it after about 2 months of the same terrible results. The other Roku "feature" was Crackle, but that's easily solved with an iPhone/iPad (or iPod Touch) and AirPlay Mirroring, so that's no longer a valid bargaining chip.
If I really want to watch Hulu, I can be patient until the Mountain Lion update comes later this year. Then I'll use my iMac and RDM Lite on my iPhone/iPad as the remote control for my Mac to watch FREE Hulu.com on my TVs using AirPlay Mirroring through my Apple TV 2 and, now, Apple TV 3. AND I'll be able to watch any other Flash-based sites to my heart's content, though they're aren't really many that I visit.
I'll most likely be selling the Roku, since it's no longer needed. The only big win for Roku, in my eyes, is it can connect to TVs that don't have HDMI. That's the other main reason I bought one at the time. Since my TVs are now all HDMI-equipped, that eliminates the need.
As noted, the Apple TV is fantastic for anyone who's into the Apple ecosystem. Even if it's just a lowly new iPod Touch, AirPlay is a killer feature that opens up so much, even for gaming.
Pros 1. Small elegant footprint; 2. Easy setup; 3. Access to everything I purchase from iTunes through the cloud; 4. Easy to use; 5. Only $99.00 (actually $85 for refurb)
Cons There are no cons.
Summary Everyone should own one. Very inexpensive and a true joy in every way.
Pros This review is coming from Canada. I didn't notice any issues wrt video/audio quality. With this device, I won't be renting any DVD's.
Cons None that I can see.
Summary What can I say, the little device is an excellent replacement for DVDs (and now that brick/mortar Blockbuster is gone, this came at a perfect time)
Pros Does what it says it does. Easy to use, looks nice, HD, it's apple.
Cons PRICE PRICE PRICE! No HULU, No Amazon Prime. HULU offers ALOT of great shows for 7 bucks a month, most from cable.
Summary It's apple - obviously it's overpriced. I love APPLE products to the bitter end, and I almost feel bad for saying this since I'm typing from a MacBook BUT this is just another overpriced apple accessory. It offers less and is 50% more than the Roku, so I don't understand why it cost so much more. Honestly your paying $50 extra bucks for the apple logo! I'll just put a apple sticker on my ROKU.
Pros the air play option with your iphone or ipad
the music movies and tv shows
small and quiet
Cons hulu plus is not available unless you use airplay on your iphone or ipad
amazon streaming for prime members is not available
needs more apps
Summary overall we really like the interface and the size and how silent it is
