So I've been digging into Python more and more, and upon Jorge's recommendation, I picked up a Kindle edition of O'Reilly's "Learning Python" by Mark Lutz, as well as the "Pocket Reference" edition.
What boggles my mind, however, is that Amazon has an Android-compatible Kindle app, yet no native Linux app. Since I'm much more comfortable doing development in Linux, I needed a way to read my Kindle book via Linux so I didn't have to squint at the 4" screen of my Nexus S in order to read. Perhaps Google IO next week will surprise me with a free tablet, but I'm not holding my breath.
Wine 1.3.x to the rescue. While it's not the 'stable' release for Ubuntu (at work) or Gentoo (on the laptop), it will allow you to run Amazon's PC application which is a free download. And it works very well. Everything sync's up just fine, but I'm still disappointed that Amazon, who seems to love Linux for their EC2 platform and other AWS services, would forego a native Kindle app.
