I have an Aunt who is still convinced that if you somehow rig the microwave to run with the door open, it will vaporize everyone in the room. 
I use mine for steaming veggies all the time. Reheating leftovers is another use.
I don't find my popcorn as dry and crumbly, maybe it was the brand you tried Brook?
My microwave also has a toaster built into it which comes in handy, but by far my favorite feature is that it has a separate built in timer. In fact, I use the timer more than I use the microwave itself.
