I am thrilled with the PS4 and actually just preordered from Best Buy...however this system is not perfect.
Used games may still have problems. Sony has said it will allow publishers to add DRM to their games if they wish. Sony will not do it with their titles. So companies like EA may still have some restrictions for used games. Not sure how they would enforce it, but it may be something like a PC where you have to use a code. Hopefully it's just like it is now, you have to buy activation codes to enable online features
here is one of several articles I've read on it:
