So I really like the new Apple TV, but there is no jailbreak yet and thus no additional codec support. So should I wait until there is a jailbreak and go with the new model or try and score a cheap previous gen model on Craigslist? I know the older model can be hacked to support Xvid, Divx, and an external hard drive (which is what I'm after) but I've heard the internal specs are a little weak for HD video decoding. Is the new Apple TV a little more powerful with the A4 or will the difference in specs only be seen with streaming (which is what the new model was designed for)?
