Capitalizing I

Does capitalizing the pronoun I feel like aggrandizing your own self-importance? Timna, an English Composition professor at an Illinois community college, reports that a student refused to capitalize this first person pronoun, arguing that to do so was egotistical. But it's a standard convention of written English going back to the 13th century, and to not capitalize it would draw even more attention. When writing a formal document, always capitalize the I. It's a pronoun, not a computer brand. This is part of a complete episode.
