3G is optional non contract month by month basis with tiered data plans. There is a price cut coming soon, one that will probably eliminate the wifi only option, so you should be able to pick up a 3G version at no extra cost soon. Memory is expensive but you can always hold out until a good sale or a price cut. Just look for a bundle that includes a card. You will be able to stream PS4 through remote play, non cloud. Through cloud you will eventually be able to play PS1, PS2, PS3 games. PS1 classics are available right now just like PSP, through emulation apps. The future looks damn bright. The system is top notch and geared to improve through updates. LBP Vita is really awesome. End result for Vita games will surpass the PS3.
Before the PS3 everyone was nice to me :(
