What the hell is the deal with Wacom stylus digitizers?

What's so good about it? I never understood this crowd raging cheer for a tablet that has stylus (wacom) support, that all started from surface pro 1.

Taking notes on an 8inch screen? Is it that accurate? I need to see what the rage is all about. As someone who's never used it, i really don't get it at all. Is it overrated? Someone please explain the hype
