You can use folders and subfolders.

But, using KOReader on the PW means that you lose the use of the native reading software. The idea here is to do it natively and not with a third party solution that changes the reading environment.

Most Readers do not support directories. They support collections. As for Kobo, Calibre can manage those collections with no need to jailbreak. Kindle's need to be jailbroken to have Calibre manage collections. So if you buy a PW2 you could get a device that cannot be jailbroken and if you buy a Voyage you will get a device that cannot be jailbroken.

Kobo collections just work. The new forthcoming Glo HD (same screen as the Voyage at a fraction of the price $129.99) will allow Calibre to manage collections. The voyage, no way since the 5.6.x firmware and Amazon plugging all the holes that allowed for jailbreaking.
