Of course, I like the fact that the iPad 3G can connect to the Internet anywhere a cell phone signal is available. But right up front I'll tell you that 250MB won't be enough for many people. I got my iPad 3G last Friday and used it a while in the afternoon. The next morning I checked and found that I'd already used 47MB of the 250MB that I had paid $15 for.
