There are no valid points in this article.
1. The interface is extremely easy to use if you stop trying to use it like Windows 95, which seems to be the world you are stuck in.
2.The lock screen fails to tell you to do next, because anyone who has ever interacted with a computer knows to press a key or click when they encounter a locked interface. Not just phones, thinks screensavers. If this is a confusing concept, you should retire.
3. Touch is not required, so I'm not so sure why this guy is so angry about the addition of a way to interact.
4."OMFG!!!!! cloud connected apps require an account!!!! and I have to use them!!!!" Again, just because a thing exists does not mean you have to use it. If you have a different application, install it.
5.Closing Start menu apps took about 5 seconds to figure out without wasting a page on instructions. EX: "Oh, when i move my mouse to the left a recent apps thing pops up... and to the right I get a control Menu. I wonder what happens when i put my mouse on the top of the screen? Oh a hand, I can move this around and pull it down to close!" Seems like maybe you NEED a beginner interface guy, ever heard of curiosity?
6. "I don't want to memorize key commands!!!! I don't want a touch interface!!!! keyboards are dumb!!!! MOUSE ONLY FOREVER!!!" Apparently the only acceptable interface to this guy is a mouse, he refuses to learn keyboard shortcuts(that are in every version of windows btw, so maybe NOT learning them is the actual waste of energy)
7. The had to rename it because of a lawsuit.
8. The next several pages are just bitching about how the past was different and how there is no start menu, even though you've spent the previous pages talking about how its all that exists now, and how Linux won't work because he watches Fox News or something.
In conclusion, according to a guy who has a website that looks like it was on GeoCities, the Windows 8 interface is both designed for children, but also too complicated for him. He needs to do real work, so much in fact that he only interacts with the user interface and makes no mention of the underlying improvements to the operating system. He laments having to use the start page to access all of the apps that he can now access from just the start page. He is so mad that you can now use touch in addition to mouse and keyboards, but is furious that he should know how to use the keyboard, and that he often has to move the mouse(even to the side OF THE SCREEN SOMETIMES! Can you believe that shit?)
Also, that pain in your leg, may be an embolism or deep vein thrombosis. It is often the result of sitting int he same chair since the 80's letting the world run past you.
