One of the most problematic new user challenges in Linux is the problem of codecs and DVD playback. These are major challenges, since they cannot be legally included with existing Linux distributinos without paying a per-user license fee.
That sort of thing is, obviously, not very fisable, but it is important to make it as easy as possible to have DVD playback and codecs for other media installed. Perhpas a separate commercial version that inludes these codecs would make sense, or perhaps the OS should just make it easy to purchase these codecs whenever you want.
The point is that being able to play media and DVDs is very important. One way or antoher, everything has to be lumped together, so that users can grap everything they need in 5 minutes with a relatively small amount of money.
