Here’s some free versions of Ong’s Hat for Kindle and as an ePub (for iPad, Nook, Sony Reader, Adobe Dimensions, et al). I’ll be putting these up on the newly redesigned incunabula.org (see design here) in 2012. Thought you might want to grab one now as my holiday present to you. Thanks to Matt for doing the great work to get these done. If you would like your Kindle edition (free or otherwise) of Ong’s Hat signed it is now on Kindlegraph.
