Since we are talking about technology I have something to contribute.
I recently bought a 4th generation Apple TV.
and a ROKU 1
APPLE TV
FEATURES:
Apple TV has a neat feature that allows you to use voice to search for movies and shows. What is really nice about this feature is it will show you the services that have the media. If you were thinking about renting through Apple but it is free on Netflix or Hulu it will show up as an option. I find it easy to scan for parts of a movie using the touch pad. I find media loads fast. Apple TV also supports games.
REMOTE:
I hate the remote. Some may like the small slim size of it but for me I found it to be problematic. I have had it slip off the arm of my recliner and slide between the side and the seat cushion for instance. It also randomly fails to turn my TV on/off. Another complaint I have is the remote is rechargeable however, you can't simply change out batteries when they get low. The batteries do last a LONG time between charges however.
SERVICES:
Apple has a good selection of services. However if you use Amazon or VUDU frequently look elsewhere.
ROKU 1
FEATURES:
The best "feature" I can think of is this unit can use HDMI and composite cables so it is usable with older televisions. I find scanning for parts of the show just as easy but less precise on a ROKU 1. ROKU 1 also loads media slower.
REMOTE:
My main complaint about the remote is it lacks volume controls. Other than that it feels nice and works well. When you make a selection on ROKU the TV makes a sound confirming your selection. That is a nice touch.
SERVICES:
ROKU 1 also has a good selection of services. Including Amazon and VUDU.
I will say overall (though the review may not reflect it) I much prefer the ROKU over the Apple TV. I just find it much more user friendly. I would also remind the reader ROKU 1 is a 1st generation device vs. Apple's 4th generation device, so the Apple device had an edge on load times. I am sure newer ROKU units load much faster and are more responsive.
