I was walking around Portsmouth NH recently when I walked by a shop that had both cellphones and typewriters. "That's an interesting cross-marketing idea," I thought. It turns out typewriters are back in vogue with your usual bohemians. My grandfather had an Underwood No. 5 which he had gotten after college working for Foster's Daily Democrat in Dover NH. I typed most of my high school and college term papers on it. I have wondered if there was a market for a software program so that when I type on my keyboard I get the clackity sound from an Underwood. I had a Smith Corona in college myself, and a Selectric in grad school, but nothing ever felt like that Underwood.
