I wish Apple would offer a NAS like this for home, just something below the Mac mini in spec.

Here is a simple feature list:

• OS X Mountain Lion Server based
• One for two HD, different capacity
• Could be used as a Time Capsule
• iTunes Media Caching server
• iTunes Server
• Software Update Caching server
• iPhoto / Aperture friendly
• Apple TV friendly (could stream content from the device)
• iPhone, iPod touch and iPad client for management and content access
• Multi accounts support

Price? 499$ for the entry level (1 TB HD).
