Sony has to take a lot of the blame. They initially marketed the device as something that was good for playing movies and music. However, Sony in their infinite wisdom only gave the option of buying overpriced UMD movies. Who in their right mind would spend more money for a lower quality movie that they couldn't even use on any other device? It's that arrogance that motivated hackers to build tools so they could use their own legal dvds on their PSP, which in turn led to the development of game copying tools and hacking culture.
The lesson here? Don't make a device and try to rip people off with something less convenient and higher priced. There is simply no way to justify charging more for a UMD movie than a higher quality DVD movie. That's the kind of greed that causes resentment.
Not only that, the UMD uses more power than flash memory. So using the device as intended actually decreases performance.
