It's all based on the same book (Connectography). I highly recommend instead reading The Stack that just came out from MIT Press, which gives a much deeper analysis on the relationship between cities, software and geopolitics: http://thestack.org
Hardcover: £25.99
Kindle: £23.99
Does it really cost £2.00 to print a hardcover and ship it across the Atlantic, or is MITPress taking the metaphorical mickey?That's actually probably pretty close to correct.
Not defending the Kindle pricing but printing and distribution of physical books is a lot cheaper than many assume it is.
