Microsoft has just announced that, starting today, you can now pre-order Windows 8 Pro. The normal price for the disc is $199.99, but during the upgrade promotion period, the package will cost $69.99, a $120 savings. Upgrade pricing will be in effect through January 31, 2013. It's nice, but it's still a far cry from the $20 OS X Mountain Lion. If you want to get in on the upgrade pricing, head over to Amazon--you'll receive it on October 26th, the same day it is released publicly. If you'd rather to go a brick-and-mortar location, you'll also find similar offers at the Microsoft Store, Best Buy, Office Depot, and more.

In addition, you can now pre-order Windows 8 PCs from companies like Acer, HP, Sony, Samsung, and others.
