I've also got a Blu-Ray player that I got open box for $40. I don't use internet streaming on it much because all the same services are easier to use on a computer.
I love the Mac Mini in every way except for Apple's bullheadedness -- I'm behind a slow DSL line, so the "download everything" ideology means waiting overnight. If the Mini had a Blu-Ray drive, it would dominate in every way.
That remote is the worst thing Apple makes, imo.
I don't currently stream to my TV in a sensible manner and I can't work out whether an Apple TV + a TV will be worth the extra cost over a TV with streaming built in?
This is primarily how I access Internet television.
You can get a look at their App Store here: http://www.samsung.com/us/appstore.
There's a developer SDK I'd like to crack open, as it seems like it could be fun to build something for 46" mouseless screen.
It is one of the best streaming boxes since it plays almost anything without problems. Can't say that about Roku or Apple TV.
If not, it's not in the same class, but if it does, I'll have to look into it.
