I agree with everything that Jim says above and I'll just add a few of my own personal preferences.
Cut your hair standing up in the bathroom and clean up is pretty easy. Just pick/sweep the hair off the floor and put in the wastebasket. I don't even need the second mirror for most touch ups. I use that only for using the trimmer around the ears.
Using clippers/trimmers are easier than using scissors and tend to lead to less mistakes. You can actually get by without using scissors at all but most people will only need them for trimming the very front of your hair (and there is some technique involved).
All in all, I agree with his points and especially that anyone can do it and it isn't hard to do.
I also agree that once you get the hang of it, you can easily look like you never need a haircut or that you have just had one. You tend to cut your hair just a little and you do it more often so it just looks like your hair never grows.
