Seems like the opposite, at least as far as returns go. See this recent example of a customer's experience returning an item to Amazon: http://news.ycombinator.com/item?id=4091840
Also, I think few would agree with you that Amazon is annoying to use or that wanting to be like Amazon is a "bad thing".
There's money to be made in providing the best experience for purchasing computer equipment, which is what Newegg used to provide. Newegg has lost the focus necessary to maintain that experience; e.g. http://www.newegg.com/Product/Product.aspx?Item=9SIA01200095...
Yeah, except amazon has always had amazing customer service, at least for me. That said, I doubt I've spent less than $2k per year there any of the last 5 years since with prime amazon became the source of everything we used to buy at target.
