In my opinion the concept of the technology is awesome.
The realisation is something else - it is interesting it seems that building digital rights into the spec is more a problem than the competing hardware??
- and people haven't spent thousands on the players for their systems, just the screen & cables & speakers - the players have become the cheapest bit. Blu-Ray, etc trying to change that, drastically, may come up against some customer inertia, in the short term
your point about umd is interesting
