The sizes were small and the prices were large. That being said, most people with an Xbox 360 bought discs in a store.
The Xbox One makes buying digital SO much more appealing. Unfortunately my "Day One" Xbox One had only 20% left on the 500GB hard disk.
While I slept (not literally, I just didn't know) the Xbox One got an update that allows "off the shelf" USB hard drives to be plugged in and for the Xbox One to be told to install future purchases to it.
So, I pulled out a 2TB USB 3.0 hard drive that I bought but had not used. I'm now transferring everything to it.
Thank you, Microsoft. #thankyoumicrosoft #xboxone
