You've had a solid five months to make the arrangements to get an Xbox One. If you want the console immediately but have somehow neglected to pre-order it, Amazon's giving you one last shot. Take advantage of it.
Starting tomorrow, November 20, at 8 a.m. EST/5 a.m. PST, Amazon's opening up a final round of pre-ordering for the Xbox One. Of course, quantities will probably be incredibly limited, so you'll want to make sure you're prompt. Afterward, you can do productive morning stuff, like try to fall back asleep with the excitement of your impending new console.
