I just got mine Saturday and love it!
Only down fall for the PS4 is all the games are still under development.... When Drive Club, Watch Dogs, Infamous, everything else comes out in March I think we will see another "shortage" of PS4s because everyone is going to run out and buy one. Killzone and BF4 look and play great on the PS4. There is an obvious difference between the PS3 and PS4.
XBone is a 360 that looks a little more polished and has new "other" stuff. They really aren't something to write home about. Still plays and feels like a 360.
Computer geeks always side with Microsoft... There is a reason why PS4's are impossible to find and Xbones are on shelves everywhere.
