In this article, it mentions:
If the skiff's resistive touch is like the sony's, then I may have to take the skiff off my list. I was just at a Sony store to check out the PRS-900. Previously, I was very disappointed in the PRS-600 where the text looked fuzzy and the screen was dark compared to the PRS-300. The PRS-900 is exactly the same quality as the PRS-600.
Anyone have more information about the skiff's touch screen and how it compares to the sony prs-600/900? The tech spec on the skiff site mentions that it works with both finger and stylus, so it's likely it's NOT capacitive.
