A whole slew of ereaders with touchscreens are coming out in the next few months, and they're using a variety of technologies. I've been wanting to write a post about the differences, and today I came across a video that demonstrates the difference between capacitive and resistive touch screens.
While writing this post, I went looking for more information and found this Wikipedia article. I discovered that I am way out of my depth. I've encountered 4 of the screen types, which is not enough to write about all of them. If I did, someone would point out the mistakes.
