How do you typically browse websites at home? Do you play any PC video games? Steam has a ton of users.
(And if you use a table, then you could use the same table for working.)
It's true that PC gaming is as popular as ever, but I suspect its rise has been at least somewhat countered with a decrease in desktop computing at home as smartphones became ubiquitous.
And there's been a decrease in desktops, but far more households have a desktop/laptop than a tablet and it's not far behind the rate of having broadband.
Or just put it on a table.
I don't see any need to distinguish between desktops and laptops for working from home. Laptops have built-in webcams too.
I'd add a big screen or two, a real mouse, and a better keyboard. But that would take up very little extra space when not in use.
