My next guess would be the liner that keeps your tube from rubbing against the inside of the spokes is missing or out of place. I can never seem to get mine to stay put when I have to change tubes, so I've just been using heavy duty electrical tape, and it seems to work fine.
Another issue might be that something has gotten embedded into the tire that sticks through just enough to poke the tube. If that's the case, you need to replace both the tire and the tube.
As a side note, I personally prefer to use heavy duty inner tubes since they are harder to puncture. That said, when I bike it is almost exclusively mtn. biking and it never hurts to have extra strong equipment when mtn. biking. I've also heard that tires with kevlar bands in them are a lot harder to puncture. I haven't tried them myself, so I cannot say one way or the other. There are also tire liners, but I don't know anybody who has tried them.
