Every year Ewan disappears to South by South West (SXSW) in Texas with his podcaster's hat on - and every year we give him something interesting to road test. This year, the kilted road warrior is taking his turn with the Nokia E7 Communicator and in this fourth video in the series (embedded below), he looks at Layar, Dropbox, USB on the go and a novel way of charging your smartphone. All delivered in inimitable chatty Ewan style.
