Ps4 is an excellent console.It has a 8 core jaguar apu which is truly fast.8gb ddr5 ram gives this console a boost in graphics.
The console has higher resolutions in games than any other console.It is compact and light weight and can be carried while travelling easily.But the price of its games is way too much.I think it should be reduced a bit.Also price in India is also very high so one can buy it from usa to save lot of money and bring it to India.The console is fully unlocked so you dont have to worry about ntsc and pal while importing from other countries.
The controller is the best with good grip and smooth movement and its way too better than the ps3 controller.It has an 500gb ssd which can we replaced easily.The graphics are the best and console is highly optimised to run games smoothly , also it has zero lag.It can be also used as a media player.Also you can attach usb drive to it.Overall its an killer console.
