However, as good as 802.11n is, few if any unlicensed wireless technologies are completely immune to interference and range limitations, which is why the inclusion of a hard drive is a great boon for this device class. As I wrote when I looked at Brookstone's hard disk-based SongCube last fall, there are many advantages to using a "sync and store" scenario for digital content devices on a home network. These address the reliability and performance of local storage while eliminating the need to manually update a device with the latest content. Managing this cache, however, can require a bit of configuration; Apple will need to make some tradeoffs here.
The second advantage Apple TV will have over other digital media adapters is commercial video content, or at least easy access to it. Because Apple has become the leading seller of Hollywood TV shows (followed by the recently launched Xbox Live video service), consumers can queue up TV shows or movie purchases and have them delivered to the big screen. Apple is clearly hoping to jump-start a virtuous circle here, in which the availability of a clear path to the television spurs demand for digital content, which spurs demand for Apple TV units.
It's a more direct relationship than Apple has enjoyed with the iPod, which didn't rely on the iTunes store for its meteoric rise. The Walkman provided a clear model for the success of the iPod. There is no such precedent for Apple TV and consumers have yet to express the collective need to move PC-based content into their living rooms. In fact, in some ways the Apple TV model reverses that of the iPod, and is one in which digital content purchases will have more weight in spurring device sales than vice versa.
Third, AppleTV will enjoy distribution in Apple's phenomenally successful retail stores. Previous DMAs have proved flummoxing to retailers that wrestle with whether to put them in the networking or AV departments. Demonstrating AppleTV effectively may not be simple even for Apple, but its retail stores' simpler focus and knack for attracting those interested in the digital lifestyle should help Apple TV's entry in the fledgling category.
Unlike the iPod (but like the iPhone), Apple TV will be cross-platform from its first day on the market, continuing Apple's embrace of the tremendous base of Windows users. But there will be other requirements that the first iPod didn't have -- broadband and a home network, the latter of which exists in about a third or fewer American households. In such homes, Apple TV will test whether the challenge to bridge the PC and TV has been due to lack of design, lack of content, lack of appropriate shelf space or, in Apple's worst case, lack of interest.
