The problem I see with the electronic logbook is will you be able to access it in 5, 10 or 20 years time when the computer hardware AND software is going to be so different. You are now caught in the software upgrade cycle for this to happen. Being a lazy sod I like the idea of just pushing a couple of keys or even better, a couple of mouse clicks and have all my desired times printed out all nice and neat. However over the course of my flight time, my blue cardboard covered logbooks are going to be oh so cost effective (even if they are a bit musty smelling).
The real positive side of the electronic logbook is the ability to back the thing up and have multiple copies. If I lose my present hard copies, it is almost back to square one and I will no longer be able to see any comments that I made when I first soloed or the doco glued into the page when I passed my CPL Flight Test. Maybe time for me to fire up the scanner and get a record of the "early years".
