Platform agnosticism and the Kindle

"...why can't it figure out that I don't want a Kindle and actually resent the thing? I am not 'platform-agnostic.'" -- That quote comes from Robyn Blumner. I found it fascinating because it seems in direct contrast with the late Marc Orchant's love for the Kindle, as described on his blog Platform Agnostic. This makes me wonder if Marc's love for the device was directly connected to his tech agnosticism, something that had not occurred to me before now.
