Is that actually true? I would think that it would be fairly common for normal people to have both a desktop and a laptop, at least. Or maybe my friends are just too nerdy.
It's far more common for someone to own a desktop and a tablet/smartphone than a desktop and laptop. Forums like this one are a poor reflection of the overall user base due to its users generally being more tech savvy and leaning more towards the prosumer side of the audience rather than the casual "I use my machine for email, paying bills and reading" crowd.
