UDPATEx2: Several Apple TV hacks already appear on the Internet, among them, the addition of more codecs [1] (Xvid, DivX, using Perian) and hard drive upgrade [2] to 120GB. It also appears that a rip of Apple TV's OS has already been posted on some illegal sites.

UPDATE: Gizmodo has posted more details [3] as well as a video [4] of the setting-up of an Apple TV.

As first units of the Apple TV started shipping yesterday, many press and online publications have already received one and provide further details on the new product.

Wallstreet Journal's Walt. Mossberg, who has received the product 10 days ago has posted a detailed review [5] of the product. He's overally positive on the product because of its ease of use and overall quality of experience though he points out some limitations such as the inability to stream video content right from the Internet or the lack of support for older TVs.

A last but not least detail also pointed out by Walt. Mossberg is that the Apple TV is running a stripped-down version of Mac OS X, confirming a report [6] MacScoop has published at the eve of MacWorld SF 2007.

Gizmodo has received [7] its Apple TV but has only some unboxing pictures to show us for the moment and points out that the devices ships without any cables for TV connectivity!

Apple itself has added additional information on the product through an updated dedicated page [8] on its web site. We can notice that the Apple TV can play H.264 videos with a resolution of up to 1280x720 pixels. The site also provides a VR view of the product.

After being delayed, the Apple TV is now available through the Apple online store [9] and should also be available in Apple's physical retail stores and other resellers in the coming days.

Analysts have high hopes on the device, they believe that it can revolutionize the movie industry just as the iPod did with the music industry. Some of them are expecting Apple to sell several millions of the device yearly.
