A-TV is only usefull for iTunes countries

Question

I assume the Apple TV product is only useful with iTunes and if you are in a country where the iTunes store is available?
Otherwise it is useless!

Answer 1

Not to be too pedantic, but whether AppleTV "can be used" or "is useful" in countries without an iTunes store are two separate things.
AppleTV "can be" used for as long as you have any content delivered via iTunes.
Whether AppleTV "is useful" when you cannot purchase content (especially video content) from iTunes Store is a matter of subjective opinion. If you can’t buy movies or TV shows from ITS, you would of course have the option to rip your entire DVD collection, then have it stored and sync’ed / streamed to the AppleTV. But,
1. Whether the convenience of having your collection organized on your computer and cycled through the AppleTV justifies
2. The effort needed to rip the DVDs as well as the loss of standard DVD features (e.g. chapter points, switching through various subtitles), loss of surround sound / 5.1 output and potential loss of video quality (if you need to conserve space on your storage medium)
is a matter of personal taste.
I kind of like to think about it by making it analogous to ripping your CDs to iTunes. What’s the benefit of ripping the entire collection when you could have just popped individual CDs into your CD player? Well, things will be better organized, you don’t have to look for 1 CD out of potentially thousands, and you get to sync your music to carry on the road.
But where the analogy breaks down with the AppleTV is i.) probably most people don’t own nearly as many DVDs as CDs and therefore much less need for sorting; ii.) it’s not as if you are taking your DVD content “on the road” with the AppleTV, unless you also own a video iPod; and iii.) not being able to retain surround sound, chapter points etc. and the inferior video quality is a big deal.
I therefore personally think the AppleTV is only worth it if you have a good source of video content that could have resided only on your computer (e.g. iTunes TV shows, things like online video content if AppleTV ends up expanding its functionality, etc.), but if one could only rip existing video media “just for the AppleTV” then the value proposition is not nearly as good. This is just a personal opinion of course!
