It didn't change the world. The iPhone did 10 years later. I guess the article is of interest because it has this wrong claim weaved in and even at it's time the "Nokia Communicator" wasn't a big success. Maybe we didn't know what FAANG-like success looks like at that time and everyone thought "Nokia is such a respectable, successful company in Scandinavia". Probably the article is of interest now because, we didn't see 2006 (year the iPhone came out) and all the years after.
Shrinking a laptop to the size of a telephone wasn't the right thing to do.
