I'd like to voice some of my favourite PS4 features:
Headphone/mic jack allowing me to listen to the game without the need of a dedicated headset is an absolute epiphany. You need to change the audio output setting for this to work.
Background downloads: this is amazing, not having to worry about pesky downloads is great. I've synced my phone to the PS4, so I've been able to set my PS4 to download a game while I'm at work. Just amazing. I wish the app didn't have to open a browser for this though.
Vita streaming: this works pretty well for Resogun and Lego Marvel. I wouldn'trecommend it for shooters mind. I've got my PS4 connected directly into the router, but I'm not sure whether the PS4 is connecting directly to the Vita via wireless, it seems as if I move from the PS4 I have problems, not if I move from the router.
I'd like to see games and even the OS use the touchpad of the DS4 more. Seems a bit wasted at the moment. Only one of the free-to-play games have used it properly.
Being able to use the motion sensors for text input is great, saves a lot of time. I click the right stick in to get this to work.
Anyways, I'm rather happy with this purchase. Feels like a proper console, even more than the 360 did. Gives me a feeling of the good old days of gaming. I just need some more games now.
Can't wait for mine to arrive! Next week can't come soon enough.
