Just for what it is worth, above my head at this very moment, on a shelf are my three, bog standard, hand written log books.
They cover thirty six years of flying and are a kind of almanac or diary, with every hour and type flown as well as every unusual event recorded too and once you retire the log books, a few pictures, lots of memories and no money are about all you have to show for it!
I have frequently referred to mine to clarify a question or two, and browsing them can evoke some great memories.
I appreciate that the computerised log book is 'state of the art' especially if you can run it from a hand held device etc. but think hard before you abandon the hand written one, in thirty or forty years time a computer print out won't mean much.
(And some employers are not too happy if they are presented at interview stage, either).
