Got my system yesterday. As of now, i have no problems, controller is working fine and wow is it amazing !?! online was perfect to me, downloaded Killzone, COD Ghost and NFS Rivals. It was very fast, i could play Killzone and COD campaign after 20 minutes, i was amazed by how everything went smooth.
I gotta say, i'm damn impressed by the PS4 on pretty much all fronts !
UI is damn fast, simple, easy to use. Some things need to be more organized like the downloads. I couldn't see the multiplayer portion of Killzone downloading but when you are in the game and want to play multiplayer, it tells you that the multiplayer portion is downloading. Why can't we see it in the downloads section is something i don't like. Also, i hope we can organize our games library soon. Right now it's ok but when i'll have 30+ games, it's gonna be a problem.
Tried party chat yesterday with 3 friends and wow, it worked perfectly, voice is clean and setup is plug and play, easy !
PS Store is way way faster now, it's actually incredible but some section still have that little lag, i guess a future firmware is gonna fix that.
Controller is probably the best i've ever used and i really liked the 360 controller last gen. The dual shock 4 is just incredible !
System is small, classy looking, silent and good looking !
Playing Call of Duty in 1080p is amazing even though the game still isn't a graphics pusher. Killzone SF is just jaw dropping ! damn those graphics... WOW !
I haven't played NFS Rivals yet because its still downloading but i heard from a friend of mine that it looks incredible.
All in all, i love my PS4 !!! Work days are fu**ing long, i just want to go home fire up my PS4 and play all day !
