If I had to rename "Smartphone" I would call it "Personal Computer". My phone is way more "personal" than my desktop and laptop.
But there's absolutely nothing wrong with "Smartphone". Two are the reasons:
1 - There's history there. Most of the words aren't precisely crafted by linguists when society needs them, we simply build on what already exists. The so called smartphone came from the cellphone that came from the telephone, the name itself hints you about its origins. It's fascinating what you can learn about a word when you study its etymology.
2 - Meaning wise I wouldn't worry so much about the connotations that the author mentions (I wouldn't worry at all). I'm with Wittgenstein in this one: the word means whatever we decide it means.
