I am sad that cellular modems in portables isn't a bigger thing. It was a feature before it's time. Now that the world is far more interconnected than before, it would be more useful that it used to be.
On the other hand, seeing that I always have my phone with me, I don’t need my cellular connection with my iPad either and I could save that $20 a month.
I do wonder if even T-mobile would be as generous with data with a laptop as they would with a tablet.
Most Windows users especially do seem to at least carry around a mouse with their laptops. Carrying a 2/3 pound - 1 pound iPad in your laptop bag is also something a lot of travelers do.
