Pros: media options, quality titles
Cons: user interface needs work, needs DLNA, no customizability
I decided to get one because I wanted another 3D Blu Ray player for the house. I have a PS3 but that gets moved around all the time. I thought to myself that I could either spend $100 on a 3D Blu Ray player, with limited video streaming functionality, unresponsive controls, and no USB photo support, or I could spend the extra money for a PS4 and have a powerful processor (which makes all the difference in the world with streaming) and a quick and snappy GUI. Since Sony just updated the PS4 to play 3D Blu Rays, now was the right time to buy one. On the gaming front, Sony has the best exclusives in the industry. Between Naughty Dog, Sony Santa Monica, Sucker Punch, and Insomniac, you could acquire a nice library of just Sony exclusives and feel satisfied. Sony has the capital to support high quality development, which is why you have games like The Last of Us, Uncharted, and the God of War games. I'm very excited to see what Sony's talent creates with this console.
But there are things that need to be changed. The GUI is a bit clunky. There's very little organization of things. The only things that are organized with their own nice menu are video apps. Everything else is cluttered on the front of the UI. This is something that will probably be fixed in the future, but for right now it's a bit of an annoyance. Another small issue is that there is no DLNA support so my Synology Diskstation can't be connected to it. So I'll have to wait for them to add that in before I can watch downloaded videos and view photos from it. I could put them on a flash drive and then on the PS4 but that's too much work and I'm not going to deal with that. The final small issue with the console is that there is no customizability of the home screen. I have photos that I like to use as wallpapers on my PS3 but on my PS4 I can't use them yet. I have a feeling that the new 2.0 update is going to allow this because there are supposed to be big changes coming for it.
I have no opinion of the controller. It works, feels nice, and the touch pad is a nice way to type. But none of that stuff is a deal maker or breaker for me.
edit: Another bonus is that it uses a simple power cord. No big brick PSU to deal with. All I did was remove my PS3 with the power cord still in the wall and replaced it with my PS4.
another edit: I will concede that I'm bias towards Sony's developers, but I have good reason. But yeah it is personal preference and some people might not like them. But it's The Last of Us, a game that made me, a pcmasterrace person say, "Ok consoles have something that we don't have and I'm jeal."
