I am very happy with Mobile Me and my 3G. Everything works and syncs well. I set up everything over wifi at my home office. After the first 24 hours, everything works smoothly and quickly. However, when I was traveling (in and around NYC) over the past two days, I've noticed that my 3G was slow to sync, Apps were terribly slow to download, email wasn't always smooth. So my question (in an effort to understand the apparent wide range of experiences) is whether some/many/most of the problems some people have reported are a result of Mobile Me or ATT? Any one else care to speculate or comment? If your having probelms, are you connecting via wifi or ATT 3g or ATT EDO?
