Digital Trends: Xbox One S All-Digital Edition review: No-Disc Dystopia.
Personally, I think the price point is the whole deal here.
In concept the game discs are a nice idea, if you can't handle downloading 60~80 GB in a single day beacause of your limited internet connectivity. In practice the disc is little more than a license key, for most games: you will still have to download enough data that it may as well be a small menary card with an activation code. For smaller titles the download might be a DVD or two worth; for big famous games it will still likey be Blu-Ray sized.
So really, all you are doing is making it so the disc must be in the drive to play, in exchange for being able to sell or trade the game in the second hand market. That's great if it is something you will play once and dispose of next week. For the rest of us, we will probably take whichever one costs less or won't require pants.
The reallity that the game will be complete and never in need of software updates is far more dead than releasing games on disc. Sadly IMHO, but at least we live in a world where publishers don't have to snail mail you a floppy diskettes in x weeks before you can get through that dungeon without a glitch making your sabatons fall off, and your character endlessly spin eastward for the rest of the game.
For me personally, the win of my original model Xbox One having a disc drive is the ability to watch movies on Blu-ray. All of my other devices are limited to streaming files from my server or external services like Netflix; most of my devices don't have an optical disc drive. And the one that does it's used for ripping discs for my private home streaming needs. I don't think you could walk into Walmart and expect to find a cheap ass Blu-ray player back when the Xbox One launched, so much as a free to good home VCR at the dump.
