I am looking for a responsive slider that can take text instead of images
There is a smaller group out there Theme Boutique who built a really remarkable slideshow tool called the Revolution Slider.  It's currently out ther and available on their Dawn Responsive theme (I have used their BigWig theme in the past with the same slideshow).  It worked really well and didn't require alot of the gymnastics that I've seen with other solutions.

Here's a demo video of it in action.  https://www.youtube.com/watch?v=zZL2renvh5o
