Well, after having a PS3 for almost 2 weeks, my main complaints against PSN are:
1) Hardly any communication in online games, and when they do, there's weird ass noises going on.
2) Not enough content.
3) Download speeds are hella slow. It takes forever to download a "patch" or "update." Not to mention installing it.
4) Installing after downloading a demo?!
5) Multiple game ID's to play a game. Metal Gear Online required a long registration that spanned 3 ID's to be created. Like WTH?! Would it be so hard to just use your PSN?
EDIT: I sounded kind of negative so I've decided to add pros so I don't get crucified.
Now the plus sides,
1) Free is always better
2) Less racist jackasses using profanity.
3) Virtually lag-free (kind of the same as Live)
4) Oh, and they charge with actual currency ($9.99)
