Some responses could almost have come from Epson employees, not from critical users!
You asked a question and you've had a range of replies disagreeing with your point of view. The responses don't come from Epson employees, but from people with a pragmatic understanding of how these products are sold. There's nothing to be gained from being unnecessarily critical of companies.
If most of you consider this to be fine Epson customer service....?
People here have given you examples of excellent customer service from Epson on the things that
really matter, continuing software updates, repairing warranty issues etc. I even had a free half day printing course when I bought my 3800.
Expecting that every product has to have it's documentation rewritten and replaced when other companies change their products is an unrealistic expectation.

An ironic comment, given that all but one of your comments have grammatical or spelling errors.
