2. yes, if you count the electricity used to power batteries that make laptops portable (disconnected from an electric power cord).
But on #2 do people often buy computer's for their own use?
In the 1960s and 1970s, computers were usually bought by governments and large companies and used for government, military, and business purposes. For example, in the Bank of America building that used to be at the corner of 5th and Alvarado in Los Angeles in the early 1970s, the computer took up the entire 3rd floor!
Now people buy computers for home and business use, personal use, etc. Since about 1988, I've had 3 desktop computers and I don't remember how many laptops! Now, also, smart phones and tablets are computers, too.
So it would defiantly be all of the above?
Watch your spelling!!
The word "defiantly" is not the same thing as "definitely"!!!
