re: spellcheckers...

I can spell pretty well, but I am NOT a good typist, and I do some dyslexic stuff. It is a real boon to my life to have a spell checker working 'live' as I work. (I actually have two going part of the time.... 'TinySpell' is always there, beeping at questionable words, and in some browsers I have a 2nd one which underlines or highlights suspicious combinations.

As to punctuation: there are cases of legal documents being questioned because of misplaced apostrophes or commas. There are quite good reasons for making written words absolutely clear.

(One of MY complaints is scattering excessive punctuation about in seemingly random ways. I have seen sentences, with commas stuck in, which don't help, at all.)
