Was Windows Home Server a failure?

The last update was on 1999 and Amazon UK as one example don't even stock boxes with Home Server installed. There also wasn't much buzz in general about the product (even when it was new). Compared to Apple's Time Capsule which you can pick up from virtually every retailer stocking Apple bits.

 

Companies who are building similar products aren't using Home Server, instead opting for unknown faceless software.
