Do non-tech people even buy computers anymore? I imagine you basically have tech enthusiasts, gamers, and IT at offices buying desktop computers at this point.
One reason to buy a laptop is school/uni. After that it feels like many people move there "computing" to their phones.
Time for some Internet researching...
True. Desktops are becoming a nishe. Casual pc use most likely has a laptop. More and more just a phone and maybe a ipad or other tablet.
Yes, there are hundreds of millions of professionals who need a computer for their work, while not being techies. They write and publish, do spreadsheets, edit photos and videos, make music, make invoices, read and send e-mails and so on.
It's like asking why a non-mechanic would ever need to use a car.
I’ve never met someone who doesn’t own a computer. Every uni student owns a personal laptop. For all the marketing from Apple, the iPad still isn’t close to replacing a laptop.
