Alternatively, let's have quiet cars as we used to have non-smoking
cars. Sadly, my experience of c2c quiet cars is that mobile phone
users
assume they can inflict their conversations on everyone, everywhere.
I
have no objection to anyone using a mobile phone, privately. I do
have
problems when their calls are imposed on me.

There are now thousands of users who would find coverage useful and
would not disturb anyone.

The Kindle ebook reader comes with a free 3G data link (GPRS or EDGE if
no 3G) mainly intended for downloading books but which including a
simple internet browser. And I have just acquired one (£152).

A user could check Live Departure Boards on the way to the station
without presenting, as a smart phone would, the temptation to use voice
and thus annoy fellow travellers.

I am gathering transport related uses:

(for buses)

for a google street and/or sat map centred where you wish.
