Interface looks extremely intimidating on Premiere, I can admit that much. The beauty of it though, is it's a lot simpler to use than it actually looks, and once you know where everything is, you can absolutely run with it. And you're right, you need decent RAM if you are going to have Premiere run and render well. But I think that goes without saying....any good editing software requires good hardware capabilities.
I was scared of using it at first too. First Adobe product I had was Premiere 7.0, and I was like....wow, how am I ever going to get the hang of this? But like I said, time, practice, patience....now when I use it's like riding a bike.
