Why can't your dad keep using his existing computer? Sure, if you make your living on the computer the new laptops are great. But if he's just checking email, photos, etc - I don't know why his computer needs to become a paperweight

At some point you no longer get security upgrades. Or new web browser versions aren't available and you're unable to access certain sites. In some cases there are workarounds like installing an open source OS but that's too much hassle for most consumers.

Specifically because in each case, no updateable web browser was available any longer. To have your main machine increasingly unable to render web pages, and to suffer growing security vulnerabilities, pretty much bricks the machine for any purpose other than a scanning workstation, etc.

Fair :) I was overlooking that this latest computer could be an older intel machine that didn't receive the latest OS, thus won't still still have years of security only updates.
