Should I get Illustrator for making posters?

I'm currently a Publicist for an organization, and I've been making posters for things using Photoshop Elements 8. I've been looking up about Illustrator and it looks like I'm going to get better, cleaner, nicer results using Illustrator for posters/headlines/logos, etc.

But how different is it from Photoshop? Is it hard to use, compared to Photoshop? Please help! :(

Speaking as a person who added vector graphics to her list of skills, it's great for those things you've mentioned and more (even pamphlets, flyers, etc.) but it's nothing at all like Photoshop or any raster art program. Get a good book with lots of step by step tutorials or, better, take an online class with instructor interaction. At the beginning, you're going to feel like you're back in Geometry class:-o but with a little practice you'll master node editing and will be able to create some very good looking objects.

Photoshop wasn't easy to use when you first started using it and Illustrator is not going to be easy to use at the beginning either. You'll be taking your baby steps with it but ultimately you're going to be doing much better (crisper, cleaner looking) work with it.

The Classroom In A Book series is a good way to learn Adobe products. The Illustrator version got low marks from Kindle users because there was no link to download the lesson files. Those that bought the paperback book gave it high marks.
