i dont buy newspapers at home, sometimes pick up a free evening standard or metro but not often, preferring to "read" the papers on-line.
while i am away i do buy a paper every day.it costs about €2 and although dearer than in the uk i do not think it too expensive. i do like to keep up with the news.
i rarely log on to the web on holiday, as i spend nearly all day on computers, but i do want to be aware of anything major happening that could affect me while i am away.
i think that knowing about things like the ash cloud and the bad weather etc in advance at least gives me the option of getting a plan b in place before i get to the airport.
besides that i can spend a pleasant hour sitting outside a cafe/bar in relative peace without being asked to do things like washing up, as all men know that going to buy the paper can take a while abroad, as you have to wait somedays for them to be delivered
