I am a huge Sony fan, PS1 was my first console. A fully BC compatible PS4 would make me buy one this instant. I'm a huge retro gamer and still collect for PS1, PS2 and PS3. I have all those consoles(80GB PS3 though, no PS2 play) and a PS4 that plays PS 1-4 would allow to enjoy all the playstation generations in 1 system.
I go to college 10 hours from home so that would be very convenient instead of needing a PS2, PS3 and PS4 to play all Sony games. The Fat PS2 and PS3 could die, so I want to use them as least I can...PS1 is fully cleaned out and a new laser...
I know they are trying to sell their crap streaming service but I don't buy digital(collector). Seems like they would sell more systems for those who want an all in one. Sorry Sony, but Playstation no longer does "Everything." Embarasssing that it won't even play PS1.
Bought a wiiU right away since I could wrap up my wii backlog and play new games. PS4 just isn't worth it now.
