Having never gotten into the habit, I just don't see the point. I understand that some people feel like they need it to function properly, but isn't that easily solved by getting more sleep?

Instead of staying up late doing things, I just go to bed and do those things in the morning. I find I don't waste as much time and I'm excited to wake up. Rolling out of bed is much easier when video games or a good book is waiting for me. I guess coffee could fill that, but I guess it's not as interesting to me as a hobby.
