Coffee makers are not very useful

Yeah sure it could just make you coffee while you do other things, but thats the thing, its only function is to make coffee, and you could just make coffee without the coffee maker (although not convenient). And let's just say you don't mind having and using coffee maker, some make coffee as a drink to get them through out the day on their work etc., and while time passes, the coffee gets colder which can be not convenient to some people, thats why some people go to other coffee branches like starbucks or if thats wasn't enough, the existences of instant coffee allows for easier preparation for convenience purposes.

(II am not a coffee person so I may be naive, but I don't mind people having a coffee maker, I have friends that tell me they have coffee maker or drink coffee and I don't mind, just stating they are not much useful as most appliances, give me your opinions on this)
