I think it's easy to overlook all the little things.

Sure, you could probably whip something up in an hour that did a large part of of what it needed to do, but it would be kinda crappy and half-assed.

You almost always do 80% of the work in the first 20% of the time, the rest is a lot slower, but every bit as important.

People absolutely can tell when they are using something that has thought and effort put into it, and you can't fake that.
