it'd be quite sick, i go alpine climbing in summer quite often, this means i'm usually 2weeks without a pc/electricity, so having a way of reviewing my vids/photos would be a massive ++
nothing more rewarding to end a day of hard climbing with viewing the sick shots you made around a fire/stove with friends....
last year i just shot a whole vacation and only saw the result once i got home ....
quite exciting but having an LCD would definately be better ...
