Playing the wait and see approach right now. Though if it remains true that you can still play used/rented games on the system and if it turns out that other publishers won't also put restriction on their games, I may eventually jump in.
Still, with my computer, I'm rarely on my PS3 as it is already and I don't have to fight anybody for the TV. It was difficult for me when I plugged in my PS3 to my computer monitor. I'm wondering if it's the resolution (1920x1080 PC games vs 1280x720 or less PS3 games) because I managed just fine playing Arkham Asylum/City on PC with a controller sitting in my chair, but playing Killzone 2 and FFXIII at the same distance from the monitor didn't sit well with my eyes and gave me a little motion sickness.
