Grognards, this interview is not for you.  Today I had the pleasure of interviewing Andrew Reutter, the creator of iplay4e.appspot.com/. iplay4e is a web-based app that allows you to play your character, with only your iPhone and an internet connection. In addition, the website gives you a place to store and access your .dnd4e character files. As if that weren't enough, you can also view your character in a character sheet formatted for the browser and play off your laptop instead. DM's haven't been left out either, since you can view the whole party in a "Party Panel", which can be pretty handy.

 And, by the way, he's a Mac user.
