Interesting, I am left handed, but you seem like a true true left handed. ( i can also write with both hands, both are not pretty in any case)
I can play guitar both ways, but your brain has to learn it somewhat backwards ( to me it was, since i started with right). They are more expensive, even though Gibson guitars are always expensive.
Still haven't found a mouse, but if i did find one, i would be insanely more faster at FPS games rather then slow and clumsy on my right hand and the inherent pains from my wrist.
On a side note,
* in Israel the most beautiful women are left handed, Israel has extremely intelligent people for some reason
* Left handed have a tendency to be more talented in creative world (music,art,etc, etc)
* But with this higher tendency to be better then the average right handed person, we also have a higher rate of being depressed, mentally ill and more illness then right handed people.
(even though most creative minds always have a higher rate of depression and other issues)
I feel your pain buddy, in school writing with the dam pencil and paper and smudges
