5 years ago today, October 26th, 2012, Microsoft released Windows 8 to the general public! I did the full icy plunge back then, and installed it on every computer I owned. Including my desktop, and laptops.
Windows 8 was not a horribly bad Windows OS, especially under the hood. However, design wise, it was very tablet-centric. It took some time to get used to Windows 8, especially with charms, the start screen, hot corners, etc.
It can be argued, without Windows 8, we would not have Windows 10. Also, any of the highly innovative hardware we have today. Most especially, the Microsoft Surface Pro tablets, and any of the Yoga style laptops!
