The article doesn't mention how the saucepan performs at low heat, which is a pretty important part of cooking. Especially if you don't have a great stove, the low end of the heat range will often be too hot, and so you rely on having a good, heavy, low conductivity pan that will keep its contents from getting too hot.
Boiling water quickly is nice, but ruining your custard because it boils is very not nice.
I'm pretty happy with the steady low heat I can get with a good conventional pan. But claims that this is the pan of the future will only hold up if it not only heats up very efficiently at high temperatures, but also doesn't heat up too efficiently at low temperatures.
