Well, I still think if data charges are flat on a reasonably unlimited basis, much more people will be surfing on the road. I think the rate is still high at the moment, at a price tag of least 2-3 times of the cost compared with residential broadband, not everyone would consider it sufficiently attractive.

Not everybody would consider that extra mobility is worth the extra bucks paid. But I think the case of ubiquity of cell phones today tells us this will change. 20 years ago nobody would mind the hindrance without phone access on the road, but now nearly everybody owns a cell phone and it is now considered anti-social if a person does not have a cell phone.

It's just the time hasn't come yet.

I still remember 10 years ago when I was still in high school it was an offence to bring cell phone to school, and it would be subject to confiscation if discovered (warnings issued and parents will be asked to come to school to get it back). However, it appears like today it is acceptable to carry one provided it does not ring in class.
