That's why the little red squiggly lines are so helpful with spellcheck. I don't know where I'd be without spell check.
I once dated a girl who clearly didn't use Microsoft Word very often. She wrote me a letter in word and when she handed it to me she said "I don't know where all the red squiggly lines went when I printed it, I liked them".
I don't think I was with her for her brains.
Yeah, spellcheck is awesome. Normally, I spell words correctly. Sometimes, I feel like being lazy, mash the keys so the word is close enough, then do a quick right click and select the word from the list. As easy as fixing spelling errors is, I still see a lot around here.
