It looks like the new DejaPIM release has gone unnoticed... They released version 2.0 on August 7. It is compatible with Tablet OS 2006. However, there doesn't seem to be a changelog so there's no way to know if there are new features or bug fixes. There were some annoying bugs with categories in the previous version, so I stopped using this app. Haven't really tested the new version yet, though I can confirm that it installs and runs!
