I didn't buy a single app the entire time I had my 3G. I finally dipped into the app store with my 3GS (the late stages of ownership) and realized the device is a whole new monster when you add in the app ability.

To date I have spent about $150-200.

I don't know if its me or the fact that I've been on the paid apps train for a bit, but the free apps seem to be getting less and less inspiring. Unless they are for an already existing service (ebay, paypal), the descriptions look awful. That being said I do have Zombie Farm on my iPhone (don't have facebook so never tried farmville).

$0.99 - The only app I ever bought was StoneLoops of Jurassica. It's a damn shame that app's no longer available. Nowadays, the only app (besides the standard ones) I use is iTunes Connect Mobile.
 
I have spent $250 on the AppStore.

If you're including Movies and Music then I am over $1000.
