I'm sure you will hear it both ways. I know a friend who interviewed at NWA and they chastised his logbook because he made monthly entries. No, he wasn't hired.
I do the little book thing and transfer to a master log book. I also use an electronic logbook with my pda and laptop. I log each full day of flying into my master log, not leg by leg. As stated above by others, E-logbooks makes it really easy, especially for applications, i.e., the Frontier App on line asks you to report flight time in every aircraft you have flown (!) When I interviewed at JB, I had my little logbooks, my master log(s), and an up to date copy/computer printout of my electronic log book. Vertical column totals matched the horizontal. The JB clerk mentioned how nice that was. As nice as it was, I still didn't get hired, but it made them misty.
