AppleTV 3.0 wish list:
- New customizable interface
 - Single-entry user/password for cable service related content
 - Global search
 - Apple TV specific App Store
 - Better remote (keep standard IR so A/V Universal remotes can learn it)
 - External Storage interface (so I can store all my media there and dont need a mac running to watch my ripped movie collection)
 - Modern movie audio capability: Dolby TruHD, DTS Master Audio
 - Broader file format compatibility for media
 - Boosted performance hardware to handle all of the above (chip, memory)
 
Good list... here's more wishes (but know they won't)
 XBMC (Kodi)
 Plex
 Amazon
 Vudu
Or at LEAST a way to allow users to add them on their own.
