Although I do think it's a nicely done app, I have to question its utility. Not Hipmunk itself, just the mobile part. Is there really a large market for looking up flights on-the-go? I mean, if you're spending a couple hundred/thousand dollars on traveling somewhere, surely you'd think about it for long enough to break out a laptop before purchasing, right? Or is there some other use to this that I'm not considering?
