I've hired a couple of people recently, and personally I use cover letters to see how people write. Not every hiring manager cares about this, but I will not hire somebody who can't write half a page of text without making egregious spelling, grammar and punctuation errors. I've seen cover letters that, when opened in Word, become a sea of red and green squiggles. It demonstrates a total lack of attention to detail, among other unflattering characteristics. Sadly, I rule out a LOT of applicants this way.
