I tried a PS4 yesterday in a shop. Played Fifa and Knack. Must say I was very tempted to buy one right there. But I didn't. Because honestly there still isn't that many games out and Amazon right now is technically out of stock and on there a PS4 is actually more expensive than the Xbox One. Which sucks.
It was so funny. Me and my friend were walking through the city centre talking about how we both like Xbox and on the way back from the store where we tried the PS4, we were talking about how awesome the PS4 was.
They are both great. The only reason I am even still considering PS4 right now is the price to be honest.
