I have always wondered why Apple and Microsoft don't embrace Bittorrent as a perfectly reasonable distribution method for "big bang" releases (like today). I have tried using Burnbit but it is only as valuable as there are folks who use it (Metcalfe's Law strikes again!).
I would also want to see some shas of the files distributed from Apple before I would use something from TPB.
I believe that when you buy things from the Microsoft Store, one fulfilment option is an Akamai "peer download", which uses BitTorrent internally. This was something I used a few years ago, so I'm not sure if it's changed since then.
Not only would it be a better experience for the customers, it would save them a ton of bandwidth as well. I have no idea why App Store doesn't use BT by default and fall back to direct downloading.
