I don't think anyone made that comparison. Smartphones are computers, they use the cellular network to connect to the internet, besides strictly phoning, they remain conceptually inside: - computer/internet - cellular phone as an evolution of those broader technologies, what I find remarkable is their ubiquity/affordability. As an anecdotal data point, I got my first (personal) cellular phone well in the '90's, probably 1994 or 1995, in the (late) '80's cellular phones were mainly for business use, I remember buying for the company I worked with (and BTW for a particular case where the need to reach this particular person was essential) one of these: https://www.mobilephonemuseum.com/phone-detail/4500x https://www.mobilephonemuseum.com/phone-detail/4500x in 1988 or 1989 and paying it more than 4,500,000 Italian lire, the equivalent of roughly 2,000-2,500 Euro/Dollars of the time, considering inflation probably equivalent to 4,000-5,000 today and the subscription/calls were prohibitively expensive.
