Thanks all for your comments. I have been able to put my goals in perspective because of your replies. My understanding after this post is that for a web startup, it's absolutely necessary to get a .com. My app, however, is a mobile app first and a web-app second. I'm thinking it's probably OK to go with a non .com address for now. If the app takes off, I'll consider getting a .com. Right now I should spend my time in getting the app off ground. That should be my focus right now.
