Same. The ONLY time I care about trophies is when the "you earned x trophy" notification pops up, and that's only because the trophy is usually called something funny. Other than that, I really don't care.
I also don't own a lot of downloaded games, not including dlc, but the idea that your PSN purchases might not carry over is one I don't like out of principle. Someone mentioned earlier a quote that the greatest system ever (snes) wasn't backwards compatible, which on one hand is a good point, but in this day and age where downloaded entertainment is huge and being heavily pushed by companies, there really is NO excuse for our PSN purchases to be lost because we upgrade to a new system. If they can't because of hardware issues, then they really need to find a way to acknowledge our purchases and list them as bought in whatever the next iteration of the PSN will be.
