When you compare the Xbox Series X to the Xbox Series S, the appeal of the more expensive version is obviously the increased power behind the hood, but it's also the fact that it includes a disc drive for accessing physical media.
This can prove to be a big bonus in plenty of cases, such as when digital games become delisted on the Xbox Store, or when you really want to watch one of your favourite Blu-Rays without fishing out your old Xbox One or PS4.
The problem is that it results in a higher cost, as evidenced by the difference between the $499 PS5 and $399 PS5 Digital Edition. So, the question is, should Microsoft have created a digital-only Xbox Series X?
