Speaking as an almost 50, left-handed-but-got-forced-to-start-right-handed-
with-mice-because-that-is-how-the-worked-back-then, occasional RSI sufferer who 
now switches the mouse from one side to the other as needed when the RSI 
starts to act up ...

I've never felt like the U/I design of any computer was left handed or right 
handed.  The LTR aspects of the design work because of the sequence people 
read in.  It should be (and I thought was) reversed in RTL languages.

Being someone with a reasonable amount of experience using a mouse with both 
hands, I can't say I've ever noticed a difference other than it takes a bit of 
getting used to whenever I switch.

On the KDE plasma-netbook interface you can switch windows either by hitting 
the upper left corner or clicking on the right most widget on the panel (which 
is at the top).  In that case, where I could do equivalent actions either way, 
I found myself going to the top right, even though it was slightly harder 
(requires a click) because that was how I started doing it.

My conclusion is that this is most a matter of habit and experience and none 
of us can generalize from our individual experiences about what is intuitive.  
The only way to discover that is find someone who's never used a computer 
before.  For people with any experience at all, they work best with something 
like what they've used before.
