I recently bought a PS3 and honestly I should have done so a long time ago. I've connected it to my 27inch 1920x1080 monitor and have been having a blast. I'm gonna say a ton of controversial stuff about what I've found:
1) Since I am joining the PS3 party 6-7 years late, there are a host of really good games on the market I haven't gotten around to playing that are dirt cheap. Absolutely dirt cheap grade A games. Plus they are all resellable without having to deal with DRM, activation codes, etc etc which is awesome
2) The games are gorgeous. I realize certain PC games outdo what consoles can provide, but on average, I've found at least the 3 games I've been playing to be far superior or at the least comparable to 90% of all PC games I've played. Which is a real surprise. Killzone 2 was gorgeous, FFX13 is absolutely gorgeous as well. Sure I wish I could turn up antialiasing on certain parts but whatever you know. Not every PC game is crysis 2; there are a lot of torchlights, l4ds, and titan quests out there and not so many on the PS3. For midrange PC games that are also on consoles, they are about the same or even slightly favor consoles imo.
3) Starting a game has no setup. It just goes and it just works without needing a patch right away.
4) My carpal tunnel is resolving. Oh man my carpal tunnel is resolving.
5) My room is much cooler as my 300W gaming PC doesn't need to be on unless I want to use my headphones and even then its on idle mostly
6) I can involve my girlfriend who's last video game played was frogger. She tried L4d2 on my PC and failed, but is looking forward to console games like ratchet and clank, nba live, etc etc And all she needs to do is buy a controller and come over unlike most PC games where you have to buy your own high end rig to play multiplayer.
7) But really the best thing is the games. I signed up for a gamefly test run which lets me rent expensive games. I figure I'll buy the cheap games I want to play and rent expensive new releases (as I get more and more down my PS3 playlist). There is no such option with PC games. I mean, gee can you imagine how awesome steam would be if you could rent a game like BF3 or COD MW3 or something for a reasonable price??? With your PS3 you can walk down to a redbox and pick up brand new releases for like a dollar a day! I'm very excited and will say to anyone who's telling themselves "let me clear out my PC playlist first before I jump over to consoles" or "consoles have nothing to offer me" that they are dead wrong and its very very enjoyable, cheap and affordable with the right setup.
