AppleTV please bless thee!
AirPlay & NetFlix are the two main reasons going on here.
We have some iPod Touches, a MacBook Pro, and an iMac in the house, as well as being NetFlix subscribers. NetFlix streaming will go great for "date night" where we can cozy up on the couch with the dog and cat, make some fresh popcorn, and enjoy a movie or three!
But then AirPlay provides even more benefits. Optical Audio for our iTunes music, regardless of source. Video for our computer media files. But what turns out great, is the potential for the home business. We have to train people in the house. Having the ability to play these videos on a tv, out of the way, and easier controls that swapping between multiple DVDs should be a great boon to productivity. Plus I can't tell you how many times we start a training session and find out the dog got to one of the DVDs.
Thankfully, the pets have an aversion to power cords, so we hope to make the Apple TV a happy addition to our home!
