The PS3 was released in 2006, and has been supported and usable since. The ps4 will probably not last as long, but will still last a while. I am a PC gamer and would recommend a PC purely for games being cheaper (around £3 for Far cry 3 and about £25 for a console). A PC can be upgraded where as a PS4 will be redundant eventually. If your friends are PC gamers get a PC, and if they play on console get a PS4, It's more preference. But a PC is more futureproof
