Especially if you have an induction stove, where the stove itself is hot instantly so you can pretty much just pour the water from the kettle into the pot and start cooking (unlike a resistive stove, where the water often cools quite a bit before the stove catches up so you end up waiting a couple of minutes after boiling the water in the kettle for it to be boiling on the stove again - still faster than going from room temp on the stove though).
