Not testing your software in the way your users use it is the disrespect. Not everyone has a modern device. Not everyone has 12gb RAM. Not everyone has 100mbps or even 10mbps. Not everyone has "unlimited" Internet.
If your website takes more than 3 seconds to load on the free Metro Wi-Fi, I'll go back to my search and pick a different page. If it takes more than 3 seconds to load on gigabit on a PC, I'll remember it and never click on links to it again.
If you don't respect my devices, then your work doesn't deserve my respect.
(Don't get me started on people calling themselves software _engineers_)
