I really depend on a smartphone with internet.
I access my emails in a few seconds, and doing business abroad, i need to know the exact Forex exchange rates, which is 2 clicks away.
I have Evo Wingle in the car, access Skype/Viber, so the customer don't have to spend money on phone cards etc.
When they want to see a picture of product, takes less than 20 sec to send through Whatsapp etc.
But, i am not addicted. I can live without it for like 15 minutes, then i probably go crazy. Sarcasm at it's best:)
Children under 15 should never be handed phones, ipads etc. Very bad for the child i believe.
