>>For me the basic requirements in desc order for phone are : small bar size, battery holding on for long time plus BT for car and sometimes motorcycle - Nokia E51 fits that quite well, can hold a few GB of data in a pinch (although too slow via USB2 as to be main portable data store, more of a backup) and was also WhatsApp device before Facebook aquired them and I ditched WhatsApp. Able to to act as WiFi hotspot in a pinch, but internet drains battery. Music and voice recorder functionality available, but seldom used. Can show Office and PDF in a pinch, but due to small screen only used in emergencies or bets ;-)

>For day to day use I carry an old Nokia (battery lasts about four days) and a satellite phone :-}

my Nokia 6210 was trusted companion for nearly a decade (at the end only as car phone, battery trouble) and the E51 would be going to school next year ;-)
The Symbian based phones were a sturdy lot: survived a lot of ski trips, me falling on them with bike and motor cycle and me groping for them half asleep and sending them to marble floor as a regular fitness test ;-))
