This is utter nonsense. That's the same as claiming, that the more tech literate you are, the more ugly UI you need. Ease-of-use means being more efficient for everyone. Or are most tech
literate still punching cards?
iPad is not the device you will do your tech literate stuff: you will use your computer for that.
Why do people think that iPad has to replace something? Sure, if all one does is browsing, some emails, and a couple of games, iPad may be the he or she they needs. For others (including "tech literate" people), it makes a great complementary device, best suited for browsing, e-books, etc. I wouldn't want to hack in Ruby on iPad, but when browsing on my couch with my iPad, with its IPS screen, portrait orientation and amazing multitouch UI I couldn't care less about all the freedom it has not.
