One thing I can say about Kindle: error reporting is easier.
You report problems in context, by selecting the offending text. No need to explain where - just what the problem is.
Feedback receipt is confirmed, along with the next steps for how it will be used.
By contrast, to report problems to academic publishers, you often must fill out an elaborate form (e.g. Springer or Elsevier). Digging up contact information often requires going to another page (e.g. ACM.). Some make you *both* go to another page to leave feedback and then fill out a form (e.g. EBSCO). Do any academic publishers keep the context of what journal article or book chapter you’re reporting a problem with? (If so, I’ve never noticed!)
