I should’ve clarified: I consider it relatively smooth for a technical user.
So no one uses desktop or laptop computers anymore? Who made that decision for everyone, I wasn't consulted.
There are millions of non-technical people with jobs, where they are issued a company computer.
It's conceivable they might want to access the World Wide Web on it.
Assuming they own no other devices other than a mobile phone as you suggest, they still have at least two and probably don't want to sync anything from their personal phone to a company computer.
P.S. your comment was funnier before you added the part about the gucamole
