The Portable Copy feature shown off at the Blu-ray interactivity demo
is a nice bit of functionality. Buy a Blu-ray disc and you can easily put an optimized copy of the content onto your PSP. Sounds good to us, but it really makes us wonder what use UMD has anymore. If it ever had any real utility to begin with, that is. Sure, UMD may be useful for those who don't have a PS3 and want to get the portable movie fix, but the format is losing visibility in the retail space
and even before
that, things weren't so rosy. Only Sony can decide when it's time to let go of UMD, but the first step in solving a problem is identifying that it exists.
