I bought a PS4 at launch (November 29) here and I'm very satisfied with it.
I absolutely love the design, games look gorgeous coming from a PS3 and the Operating System is so much better. The DualShock 4 controller is also absolutely amazing; the other day I went to play GTA V on a PS3 and I was just shocked by how bad the PS3 controller felt.
I'm also using it for Netflix - yeah - as well as some YouTube and VidZone here and there. Software wise, I think there's still a lot of room for improvement: Music Unlimited is not as instant as it should be (it takes way too long and way too many steps to start a song) and other features (such as local MP3 and DLNA) are still missing.
I hope they'll continue to add features.
When I'm looking at the games, I'm also quite satisfied. I got Killzone, NFS Rivals, BF4, FIFA 14 and AC4: Black Flag at/near launch and I'm still enjoying myself with those games (I haven't finished them all yet). I also put some time into Resogun and I had an absolute blast with Outlast. That said, I haven't finished all games yet: both NFS and AC4 are far from finished - not because I don't like them, but simply because I haven't had enough time to finish the singleplayer stories.
Games I might buy this year
I was looking forward to Thief, but after reading some of the previews I have decided to wait until the price drops a bit. Tomb Raider came out last month: I never played it, I'm not sure I'll like it, so I'll also wait until the price drops on that game.
I might get inFamous: Second Son next month but I'm still undecided. The only inFamous I played was the one you got for free a few years ago (after the PSN intrusion) and I didn't like that one.
I'm also undecided on The Order: 1886. I like the setting and time in the game, but I'll need to see some gameplay before I decide whether or not I'm going to buy this. That said, I'm glad to see a new IP.
Destiny, Watch_Dogs and The Crew are also games to follow - and I'm sure more holiday blockbusters will be announced and released this year.
