I'm almost 42 and I carry my laptop in a backpack. Sometimes I carry two laptops. The backpack is one of those designed to carry a laptop. I recently started carrying a full size keyboard and mouse, because I find it harder and harder to adapt to the laptop keyboard and touchpad for extended periods of time. The weight never bothers me; but again, it's a properly-designed laptop backpack. If I used a (cough) "professional-looking" briefcase or shoulder bag, it would really hurt to carry. If you really need to look professional, I suggest finding a very small computer that can fit in the pocket of a trenchcoat. Keep in mind that today's computers are very fast, so they might be "good enough" to run Visual Studio / XCode / whatever on a moderately-sized project.
