1.) It's a lot faster
Remember the days when it took forever to enter PSN and some downloads couldn't download in the background? Well, I was so relieved to find out that I wasn't going to experience that anymore using the PS4. I could now download games and updates while doing other things with some occassional bugs of course.
I also love how I can quickly go to the XMB menu, Netflix, or PSN without having to quit my game. It's a pretty awesome improvement from the PS3 days.
