Given the purpose of the AppleTV is to act as a media extender for iTunes content, what are the key limitations and issues with the AppleTV as it stands today?
Besides these obvious ones that I'm aware of, what else?...
Hardware:
1. Doesn't support external storage for syncing large libraries
2. No 1080p content playback
3. No GigE support
4. Poor remote reception
Software/Service:
1. Can't use TC or NAS directly (requires a Mac to stream such content)
2. No subscription service for heavy content usage (you have to pay for each individual piece of content)
3. Poor remote-control support for subtitle and audio track selection
4. Occasionally drop-outs from iTunes - requiring restart of iTunes/ATV (when using wireless)
Content:
1. Limited support for streaming 3rd party content (Youtube only)
2. No 1080p content available
3. No direct support for user-created content (must be imported into iTunes)
4. Content is expensive compared to competing solutions
Missing related features:
1. DVR functionality
2. Apps/widgets
3. No social-networking media sharing support
EDIT: updated per other's suggestions
EDIT2: updated primary purpose and updated lists
