I just got the 3G iPad and planning to use wifi in most case. I decided to enable the 3G late yesterday jest to see how well it works? I went to work and use it at work off and on using 3G. I was getting good down link ~2.5mps. I went with unlimited data plan. At the end of the day I was surprised how much data I have used. Within a day, I already burned up 190MB on my data plan. Wow!!! It's nice to be able to use this bad boy every where.
