Why Should I Jailbreak My Apple TV 2nd Gen?

Good rundown on Reddit. Right now the options are: XBMC, Plex, aTV Flash, BTStack – and lots of other SSH tweaks you can play with. The current Apple TV jailbreak is tethered, but it’s a better scenario than the iPhone or iPad: when the device goes to “sleep” (TV is turned off, Apple TV doesn’t do anything) there’s no need to run the jailbreak software on next relaunch. As long as the power cord is plugged, the jailbreak is on.

Personally, I’m thinking about it just for Plex.
