This morning we received word from Jesse Grosjean at Hog Bay Software that his new app, PlainText (free, in-app purchase to remove ads), is now available on the App Store. It's one of several iOS text editors that feature support for Dropbox, so we thought a quick roundup of these apps was in order. If you're thinking about joining me for NaNoWriMo 2010 starting on November 1st, it's a good idea to think about what device(s) you'll be writing on and getting your writing software ready to roll as soon as you can. Text editors make excellent writing tools, since they're bare bones and don't get in the way of putting words onto "paper."
