Yes, which is why folks will still want it (at least when using the device at home or work) for some time....if you are doing anything on the device that really benefits from the faster speeds of 100mbs or even GIgabyte networks...

Some 3G systems deliver 4G speeds. It all depends.

For faster real 100mb wireless speeds, there is promise in the future of LTE:

Still no wireless Gigabit networks though...
