Here's another perspective on Apple TV from non-Mac devotees: A reviewer at PC World took Apple's media streaming device out for a spin, and generally liked what he saw. It's a good read, praising the easy setup and straightforward operation.
But that's nothing you couldn't get here. When you go to the trouble of reading PC mags of old, you want the kind of depth we saw in PC Magazine's gonzo 10,000 word article. Then again, if you must have the most concise Windows Lover's standpoint:
Reviewer Edward Albro starts out characterizing the box as a big fish in a small pond:
"To say that Apple TV is the world's best media streaming device could be considered faint praise, the tech equivalent of calling someone the world's tallest midget. After all, most previous versions of these devices, have been unreliable, hard to use and generally shunned by the buying public."
The astute reviewer pointed out, however, the mediocre quality of program material he downloaded from iTunes, and decried the glaring lack of HDTV programs on Apple's content delivery store, particularly ironic when using this device that will only work on widescreen TVs. In the end, Albro seemed mildly impressed, but noted that Apple TV is poised for improvement.
