It will be a big selling point for both systems. I've said it for a year, I own a PS4 controller. I was really disappointed with the remote play on PS3. The PS3 wasn't probably designed for remote play and no one supported it. It was slow and lagged. The automatic start feature glitched up with routers making it completely useless and required someone to turn the PS3 on to use it away from home. What I used it the most for was accessing the PS3 store after the updates, but now the new store doesn't work with it.
With the PS4 being designed with Vita in mind, it will not only run faster as they've shown the speed of the connection it has (no more lag, yay!) but it should work entirely with the system and all its features and games (except move required ones and stuff). So it is kind of like the Wii U in that you can operate and access the console without using your tv right? Well with PS4 and Vita you can do that but from any internet connection, not just in your house.
Before the PS3 everyone was nice to me :(
