*Clap sarcastically*
This is just typical Apple though. They're milling down the product to reduce production costs and to unify the OS between the iPod Touch, iPhone, iPad and now

TV. The prospective product is, under no uncertain terms, just an
Airport Hub that can stream video instead of just music. Yet Apple will market this 'original' product as if its the new Messiah with an unprecedented use of lexis such as 'magical', 'easy', 'beautiful', and people buy in to it.
The question is, why would anyone want to pay upwards of $99 for this when:
A] Many products already offer streaming - most commonly, PS3, Xbox 360 etc... Some new TV's also offer Wi-Fi streaming.
B] It just another box sitting under your TV, only this one would have even less purpose than the others.
C] If you have a poor internet bandwidth, the already compressed video is just going to lag.
The product is only going to benefit those who would rather not us the Cloud-based service and would just stream for their Mac. Though why anyone would actually want to buy films from iTunes is beyond me... The Hi-Def titles are no where near the same quality as physical copies.
Sorry, but I'm not sold on this one.
