I have now completed the conversion and upload of a number of my titles. If you are looking for the ePub and Kindle formats of the title they are now available:
Getting Started With Companyweb 2010 (ePub)
Getting Started With Companyweb 2010 (Kindle)
This title is great for those starting using SharePoint Foundation 2010 on Small Business Server 2010 and is only $1.99 which I think is pretty good value for some training material.
Stay tuned for a few more titles that will become available very shortly.
