Once you've done that, and if you're still hungry for Apple TV news and opinion, iLounge have put together a comprehensive review and look at the new features of iOS 4.1 for the Apple TV.
The review covers the installation process, AirPlay for music and video, streaming content from iOS devices and iTunes, the new accessibility VoiceOver feature as well as a section on playing videos in photo albums (not present in the previous software).
There's also a look at some of the more minor fixes and features that will make a big difference to the everyday use of the Apple TV. For instance, there's now better integration with your iTunes library. Playlists will appear as they do on your Mac, other sorting issues have been resolved and playback status is updated in iTunes after playing media on the Apple TV, to name a few.
One glaring omission, mentioned in the review, is the absence of support for iTunes LP and iTunes Extra. Both of which were available on the first generation Apple TV and anticipated in this release.
If you're an Apple TV fan boy or girl and you're wanting a bit more nitty gritty detail on the new Apple TV update, we highly recommend you head on over for a read. Then come on back and let us know what you think in the comments below.
