Getting hot has a lot of complexity, actually: How hot does it get? How can you select the temperature and how accurate is that selection? How well does it maintain the selected temperature?

Simple soldering irons often don't even have temperature selection. And their predetermined temperature drops significantly when heat is transferred into the soldering pieces.

I can dial the Pinecil very accurately to anywhere between 100° C and 400° C, to provide the optimal temperature for the soldering job and it meticulously maintains that temperature (given the power supply is beefy enough).

Another nice feature is automatic stand-by when the tool isn't used. This preserves the tip, saves energy and lowers the risk of accidentally setting anything on fire. It automatically heats up blazingly fast when I pick it up again.

Pretty much this. Abridged for my little knowledge: I can easily set up my favorite temperature, and I can be sure that it's constant no matter how big the part I'm soldering. As a bonus, the soldering iron cools down when I'm not using it, making accidental touches less painful. Another bonus: there's a "boost" button for very stubborn solder joints.
