OK, no argues here.
I like to believe I am normal customer too, but I never believed in "one-size-fit-all" mantra.
I am also mostly using tablet to consume, but I like that I can access my media same way I'd do on laptop or desktop. My tablet fits into my existing home network, with no need to do what-so-ever adjustments to make network tablet-friendly. As in, browse my network shares and copy over (if I want to take tablet away) or open directly from the network; older TV shows, comics, eBooks mostly.
My wife grabs tablet to do quick review of assignments, MD and PhD chapters for students she is supervising.
We both print and scan on occasion to and from network attached printer/scanner.
And of course, usual stuff - web, email, FB...
Most of these things can be done from iOS and Android nowadays, but there are still some limitations in network access, compatible printers and scanners and, in my wife's case, full MS Office compatibility - she is physical chemist, some of those documents are quite full with formulas and other "non-standard" content.
I did get two iPads for my mother (so far) and I'm very convinced that was the best choice for her. She is also normal customer, only more stand-alone and less networked than I am.
I think we need to normalize what normal is. I don't know anyone, other than my geek friends, that have home networks. Most people, and by that I mean normal consumers, have 1 or perhaps 2 computers in their house. No network storage or the need to open up complicated Word documents. Scanners? They still make them? Printers have a long way to go on the tablets.
You probably fit into the more technical 25%, but your needs don't sound normal to me.
That is not to say your needs should not be met in the marketplace, and I'm glad you have found the right fit.
