LaTeX is a typesetting computer language. To use it powerfully, you have to really learn it. The learning curve can be steep, particularly if you've been primarily a casual user. It's also considered a markup language. If you've had experience with html, you may find it easier to use. If you are putting together presentations professionally (as it's in your job description), say as a junior analyst or professor, you'll find it to be very valuable. If you're a casual user, or a student doing a project here or there, unless you're doing it for the learning experience, it's much easier to use PowerPoint (or a free alternative: OpenOffice.org's Impress).
That said, there are many templates and examples that can make the presentation creation process much easier.
In summary, it really depends on your intentions and long term goals. I recommend Beamer for a long term learning goal, if it fits into your learning desires or professional needs. As a lifetime learner, I want to learn it myself, and I've made some steps along the way to learning it, but it's on the backburner for the time being.
