Where to find the best iPad accessories

With the so long awaited for Apple iPad finally here, people started to search for the best accessories to enhance their device. We are also seeking for little but important things such as a decent case, a screen protector or a car battery charger. As we reviewed a lot of those, here are our top picks, so you can save some time with your own research.
We thought Quirky's Cloak iPad case was one of the best, so we decided to go for one, as it seems to do exactly what we wanted: we can use it in both landscape and portrait view, we can adjust the viewing angle and we can look elegant at all meetings where we are going to take the iPad with us for presentations.
