If you have hard water, you'd know just how silly that question is. Everyone descales their kettles at some point, but we don't want to do it every other day. That's too much effort for making coffee or tea. The filter is there to extend the amount of time you can go between descaling to reasonable timescales.
I went on a similar kettle-quest a while ago and wound up accepting the disco-ball LED enhanced model because it was cheap and did the job (and mine doesn't beep - that would have immediately sent it back). I still think about going with the fancier one with a temp control for that perfect cup, but just waiting a minute for the water to come off the boil is fine enough for me.
