GS9, 10 next month, still reverses letters which are commonly reversed. He reads very well, but his spelling is so bad that it's not unusual for him to not read his own writing. His letters will be mixed in order and sometimes reversed.
He writes & eats left handed, throws & kicks right handed, switch hits equally well(if he could catch and throw as well as he hits, he'd be a very good little leaguer!). He still prints since they didn't seem to concentrate on teaching cursive at any point in grade school, and he forms his letters backwards -- for example, when he makes an 'm' he writes it from right to left instead of left to right. That leaves his printing with uneven spaces unless he completely concentrates on being neat.
Last year I was worried about dyslexia, ambidexterity, mixed dominance, etc., but finally decided in our case that it was mild enough to not cause him a problem.
