Nah, I guess it depends on the user. 90 % of the users are used by people who do not have the ability of using a comparator, as you said.
I mean, I've seen too many projects for which they use an arduino when a 555 was enough. However, every now and then a really good project which uses an arduino appears. If I said Atmel micro controller development board, you'd probably say its ok, if I said Arduino, you'd shout noob.

My class just had a touch project, just to prove the concept. Complicated circuit boards, 555 timers, comparators dominated - parts count was overall high. I finished this project with a single sided pcb, one resistor and a header to interface to a xplained xmega microcontroller.
Not only was the current consumption of my circuit waaay lower (due to the 25Hz update rate), it also had the highest Signal to noise ratio of all the systems. I could go on.
I could say: I think comparators and resistors are for people who don't understand microcontrollers.

I think this is a silly statement. Sometimes a micro is justified , sometimes it isn't. When it is justified it can make more sense to buy a standardised platform and build on from there. No point reinventing the wheel.

Microcontrollers consolidate fairly large, possibly unreliable, possibly expensive digital circuits into a single chip that can be reprogrammed in case of improvements or errors. How is that only for idiots?

Perhaps sometimes you're right that Arduinos are used where a simple analog circuit would suffice, but the Arduino is still a nice platform for people who just want to build projects that call for a microcontroller but don't want the headaches often associated with microcontrollers. There's a lot more to DIY engineering than messing around putting together a microcontroller board with power supply, oscillator, peripherals, and getting code to compile properly and programming it onto a chip. Arduino makes that stuff easy so that people can focus on building more complex projects.

My father (a hard core electronics engineer) has just about finished building a complicated interface using an arduino to interface PCs to legacy test equipment.
I'd love to see you try to do that with a couple of comparators.

what sort of complex projects have you seen done with a shitino? I went to my local hackers space and everybody was doing an arduino project. I think it makes electronics too user friendly.

12kw induction heater, self-locking resonance Capable of levitating aluminum, steel and copper. Capable of serving as a furnace for a blacksmith who needs to uniformly heat pieces of steel as small as a knife to as large as a full-sized sword. This project required a microprocessor. If you look at the schematics at the end of the tutorial you can see how it was worked into the project. There are YouTube links so you can see it in action.
