I don't know how old you are but you best buy 3 or 4 computers and store them away. The world is switching to touch ie phones, tablets, autos, gps, etc.
I am 73 years old, and I just recently got an Samsung, and a Ipad along with my Kindle. I am using the computer less and less now. But I will always have a computer no matter what OS release is available.
Before I install W8 I took the time to read about it on the net. All of it's changes and solutions were read about. Now you can't tell it apart from W7 or as a matter of fact from even my old Vista. I can't tell you the last time I was on the Modern side of the OS.
One can fight changes or one can learn how to use them. I repeat the future is touch.
