Mostly enjoying it when it works, but I'm getting a ton of software issues. Problems updating the firmware, problems patching a game, problems copying a game, problems IN a game. I cleared most of Astro then after installing the update it wouldn't even boot, so now I'm totally re-installing. Demon's Souls eventually loaded up and then hardlocked as soon as I did anything in the game. At one point it told me I had the downloadable version and that it needed to switch to the disc edition.
So yeah, not smooth, expected a little more when it's already been out a week. But Astro was awesome when I did get to play, the controller is bananas. Might get a bit much when you just want to grind a game out, so I'm glad you can turn it all off, but for the initial go-around it's gonna be cool seeing what studios like Guerilla and Naughty Dog do with that tech.
