I found that the 3G on my iPad is a game changer. I travel a lot and it gives me connectivity everywhere all the time. You'd be surprised at how much you use it away from wifi networks (and how thinly spread the publicly accessible wifi networks really are). If you're careful and just use it for email and light web surfing you can get away with the free 100MB per month. Just don't download anything or stream any video. There was no question that I would buy the 3G Chromebook. That's part of the experience.
