You are right Kitsambler.. in fact the phone actually weighs MORE than the paper version of the guide (at least the old 2006 version that I have been lent) but on the other hand I am taking a phone anyway so it was an unexpected bonus to find that as well as Alison Raju's guide, I could download an English French dictionary (still trying to find a French English one!), save some MP3s of French lesson to allow me to practice my French on the way, save manuals for my camera and watch, maps of the Paris metro, some English language books to read, an Fm radio, and internet access where I can find Wifi. Now if I can just learn to use all of these before next Friday..
and Falcon you are right too .. after further exploring I did finally discover a better zoom than I had previously discovered.. so can use the maps too.
