According to many websites, the HDW-19819-001 is synthetic leather and the HDW-18969-001 is real leather. If you go look at the Storm cases on ShopBlackberry.com (RIM's website), you'll see that the description of the HDW-18969-001 mentions leather and the HDW-19819-001 does not. If I had reached 10 posts, I would post links.
