I've always been concerned with the aspect of controlling playback during a listening session. In other words, displaying & browse media as it plays.
Nowadays, it's simply inconvenient:
1. Using a TV Screen / Monitor?
2. Connecting to the audio machine remotely with a laptop or a tablet?
3. Using some sluggish web interface plug-in for Foobar or Jriver?
4. Using Apple's "Remote" app to connect to an Apple machine or a PC Foobar with the right components?
I think that we're still lacking a comprehensive solution that will make this whole computer playback thing - sexy (once installed and properly configured of course). To be fun and easy to use. To look sleek and offer easy browsing without being dependent on a big screen, hard-to-configure software or solutions comprised of patches upon patches.
And what's missing in YOUR audiophile-computer experiene?
