thanks for the feedback! i added multibit as a thin client, but if Electrum isn't a thin client then what should i refer to it as? also changed slide25 to be 'misc info', and in the future i hope to incorporate it better into the existing slides. also i should definitely do a better job at mentioning places that allow people to setup stores, especially if i am talking to potential merchants.
another glaring mistake is that in the talk i say bitcoin addresses are public keys, when in fact they are hashes of the public keys.
