Well, it’s come to this. Microsoft is launching Windows 8 on October 26. But unlike many of the previous generation OSes, this isn’t an incremental piece of software. It doesn’t build on top of an old infrastructure, it makes a brand new one. Excitement and expectations are high for Windows 8 and its don’t-call-it-metro interface. And if you’re upgrading, you can get yours for just $69 on pre-order, and have a $30 Amazon gift card thrown in for good measure.
