Pretty sure I have read somewhere that some commentators have said that it requires either a firmer touch or a double tap to activate something, rather than the single light touch on many of the smartphones.
On that basis, i would say you have been spoiled :)
I have 2 kindles now - the original one, and I recently received a kindle fire, and I have had no problem with tapping and dragging - but I might be heavier- handed than you :)
