While there are times when I ignore my mobile, the fact is that quick communications are now essential in many fields. My workplace couldn't operate the way it does without the fibre-optic internet and phone connection.
I have both work and private emails coming separately to my phone and never turn it off, except if I'm in some remote area with awful phone signal (that would be more than 80% of this country's landmass, I think).
The information highway is now more important than physical highways and that is only going to get more so in the future, I think. Communications are vital to this country's future. We have to do more than just dig holes and ship chunks of our country overseas to make a living in the future.
