So I upgraded to mountain lion so I could try the dictation feature. It's actually pretty cool. Since I can't type with both hands, its faster to enter text just by dictating. It takes quite a bit of speech at a time and it's pretty accurate. I generally only have to go back and correct a couple words here and there. This whole post was spoken!
$20 for the upgrade was much better than buying something like Dragon dictation, that's like $200!
