My favourite phone is a Nokia - just texts and calls - small, lightweight and battery lasts for days. I have the sound off nearly all the time, unless I am expecting a call, and I just check from time to time when I'm ready. I have three other phones for work, two of them smartphones which I find clumsy and which I mainly use for maps and, occasionally, checking information, like when the bus is due. We have strict rules here - no mobiles at the table or in company. But then, we still play cards and board games.
