1) You can make it as strong as you want. 

2) It's a lot quicker than brewing a pot with a drip coffee maker.

3) Less waste- no grounds or used filters to deal with.

4) You don't have to clean that moldy coffee maker. 

5) It tastes just as good- just throw some milk in there and you can't tell the difference. 

If you use a drip coffee maker, after a month or so it gets really nasty, full of mold, the coffee tastes like crap, and you have to go to the store and get some white vinegar to clean it, and you never really get it clean.  Plus you have all those used coffee grounds, and if you let it sit on the burner for more than 5 minutes, it tastes like filling station coffee.  If you use a Keurig or something like that, you pay so much for those little containers of coffee it's ridiculous.
