Personally, I don't know how I feel about high-definition. Sure, it makes it seem like you're really there ... but that takes away some of the magic. The Fantasy of Television will be much more difficult to maintain once we can count our favorite actors' nose hairs. Like the Rise of Mac, however, I fear that succumbing to high-def is inevitable. That's why this "war" is such a hassle - if you're going to make me switch, at least tell me what to switch to. Not since the "VHS or Beta" debate of the late 70's has incompatibility been so relevant to our day-to-day lives.
Thanks to my brother for all the information. More can be found here.
