Seems the iPad is not what it seems to be...

"“Carrier networks aren’t set to handle five million tablets sucking down 5 gigabytes of data each month,” Philip Cusick, an analyst at Macquarie Securities, said.

Wireless carriers have drastically underestimated the network demand by consumers, which has been driven largely by the iPhone and its applications, he said. “It’s only going to get worse as streaming video gets more prevalent.”

An hour of browsing the Web on a mobile phone consumes roughly 40 megabytes of data. Streaming tunes on an Internet radio station like Pandora draws down 60 megabytes each hour. Watching a grainy YouTube video for the same period of time causes the data consumption to nearly triple. And watching a live concert or a sports event will consume close to 300 megabytes an hour."
