If you want to learn about SharePoint 2010 Development, you can start by downloading the Sharepoint 2010 Developer Training Kit.

Once you install the kit, you will find a folder (SharePoint2010Developer) on your C:\ drive (default location).  In this folder you will find training videos, PowerPoint presentations and labs.  All these files are accessble via the default.htm page in the same folder.

Here is a list of the different modules that are part of the training kit.
