Oh, and here's an interesting footnote: the original Kindle was apparently codenamed "Fiona" after Fiona Hackworth in Neal Stephenson's novel The Diamond Age. Many of the names in the device list above -- Nell (the protagonist), Miranda (mother figure to Nell), and Turing (i.e., Turing Machines) -- are all related to that very same story. What we can't figure out is how the word "Shasta" fits into all this so lay it on us Cyberpunks if you know.
Update: Freddo411 seems to have nailed it in the comments: Shasta, Lassen, and Mazama are all volcanoes in the Cascades.
