The mistake you made was that you bought a console (a great console, in my opinion, but my opinion doesn't effect how much fun YOU are having, does it?) without making sure that it had games that you wanted to play. That's why I didn't get a 360 until 2007, a Wii until mid 2007, and a PS3 until 2008. No matter how capable a console is, it all comes down to games.
But now that you have it, look at some of the features that it has: You can download games like FF7 and Metal Gear from the PSN. You can download comicbooks (my favorite feature), you can download music, and you can download movies. It can also store your pictures, has internet radio, Skype, and remote play with your PS3. It's a good piece of hardware. Let some of those features occupy your time.
As for graphics, say what you will. Those games are graphically the best you're going to find. You say that they have DS graphics, but if they're the best that are on the market then your only option is to make your own games....... But, there are a few gems that are graphically impressive like Jeanne D'Arc. Youtube a few that interest you, and demo a few games, too. You'll be surprised how many games that you weren't interested in may grab your attention. If I weren't so wrapped up in FF7 (AGAIN) and comic books, I'd be downloading Syphon Filter, Secret Agent Clank, and Resistance Retribution, right now!
Or, you could just return it. You just bought it. Take it back if you aren't happy.
