If I get a fiio e6, I won't expect an impovement in SQ, I just think it would be fun to use.
I wouldn't dissagree with pretty much everything you say but lets not generalise, what may be true for you will quite likely not apply to the next persons kit combo. All amps are NOT created equal and there are many variables that should be taken into consideration depending on the player/amp/headphone combination.
I don't have either of your devices but my laptop just has a truely aweful amp section, my Iphone 3G sounds terrible with my low impedance Iems (possibly due to the Iphones own output impedance affecting the FR dynamically?) My Samsung Galaxy S has fantastic sound quality from its Wolfson DAC but it struggles at higher volumes with my TF10's due to lack of headroom and judging from the pre-amp gains auto reduction when boosting certain frequencies with the EQ I can only conclude that the inbuilt amp just doesn't have enough power to do what I'm asking of it.
There is a good thread on the factors that can affect SQ with amps, see- http://www.head-fi.org/t/583300/what-makes-some-amp-better-than-others#post_8469465
