This is printed all the time but what does it matter? Work that used to be done on PCs will now be done on laptops or pads or from servers, thus computing product will be sold, and a lot of it by HP.

Truly, the opposite is the case, as now everyone carries a computer with them in the form of a smartphone, pad or laptop. What is lost in PC sales and use is more than made up by the growth those others. The horse and buggy gave way to the car, but people didn't stop road travel!
