To me the age of the software sounds a bit like channel-stuffing. Often manufacturers will report on devices as being sold once they've left the factory for the retail store, not when they are in a consumer's hands. Because there is great incentive to report good sales, manufacturers will often negotiate around inventory so that a warehouse somewhere gets filled with devices.

These devices then sometimes sit in the channel waiting to be sold (sometimes for quite some time, depreciating in value) but if the device flops then the seller writes it off as a loss and they go to the clearance rack.

That's why you can have amazing numbers for 'sales' and then 3 months later the thing is a well-known dud. Device manufacturers that sell directly to consumers tend to report sales when it's been shipped to the final buyer.
