Hey, author here. The comparison of Evernote to Google Docs was primarily on an enterprise/business level. While you're right, and the products aren't completely similar, Google has done well with market penetration for Google Apps for Business (at least as far as companies who aren't running a Microsoft stack). Even if Evernote is in many ways "better" than Google Docs for a particular purpose, if you have Google Apps paid for, it's "good enough" for most uses (especially sharing/collaboration). So it's equivalent in some senses, but certainly not all.
