Microsoft is, in fact, not doing as well as it should be. Global adoption of Windows 8 with its tepid reviews has caused enterprise adaptation of Windows 8 for businesses to be beyond glacial in speed. Microsoft makes the most amount of money right now with its corporate side, and if the latest iteration of Windows isn't doing hot, you can bet that Microsoft isn't having the easiest of times. It's not doing terribly, but I digress.
Most people would agree that, in a perfect world, the used game market wouldn't exist as it currently does. How it is now, and how it would be under Microsoft's Xbox One (from all the information we currently know) doesn't deal with the fundamental problem that used games introduces: a lack of secondary revenue for the developer/publisher.
Gamestop and Best Buy all make bank off of trades because whatever they sell a used game for, minus the cost they paid for the game from the customer and any kind of repair costs, is all net gain. Trading in a used game where the trader gets $10 in store credit, and $2 goes to resurfacing the disc, that same used game can be resold for $30-40 with 50-75% going right into the company's pocket. Some games currently fight this with an abundance of DLC, online passes, etc. It still doesn't make up for the loss of money the developer and publisher are deprived of.
From the current known facets of the XBO, the two most critical are the fact that there's a fee to pay to borrow or use a used game, and that indie developers are currently slated to be shafted without a publisher. Unless Microsoft announces that the money being charged for that reactivation fee at least in part goes to the developer and/or publisher, then they're doing nothing to fight the problem at its core.
To quote one of Microsoft's own sage wisdoms:
DEVELOPERS! DEVELOPERS! DEVELOPERS! DEVELOPERS! DEVELOPERS! DEVELOPERS! DEVELOPERS! DEVELOPERS! DEVELOPERS! DEVELOPERS!
The comments about the one billion consoles sold thing is at best optimistic if consoles are, from this generation onwards, considered an essential component of any media system, meaning it replaces cable boxes, DVRs, and DVD/Blu-ray players. Otherwise its just a stupid number.
