since they logbook pro is being stupid and not going after the ever growing mac market.
Then use a web based logbook. They'll work on any platform that can run a web browser. Thats everything from Mac to Linux to DOS to Amiga. Plus, if your computer/iphone ever craps itself, you have the flights stored at a different location so no data is lost.
The way I see it, there are three advantages of using a electronic logbook over a paper logbook:
1. Easy totaling - Instead of spending hours adding up columns with a pocket calculator, an electronic logbook does it instantly without ever making an error.
2. Neatness - No worrying about your logbook looking like crap because your hand slipped when making an entry, or having to use whiteout when you accidentally wrote a time on the wrong line.
3. Data protection - Electronic files are easily duplicated and therefore can make it so you'll never have to worry about losing everything.
Logbook Pro and other such products that basically are just fancy database front-ends, do not provide any data redundancy. If you computer crashes, you're just as screwed as you are if your flight bag is stolen. Most web servers these days have double and sometimes even triple redundancy backups, so nothing will ever happen to the data. The best you can do with Logbook Pro is copy a backup onto another hard drive, or email it to yourself often, but thats a pain in the ass. Even then you can only go back as far as the last backup you made...
PLUS, all the online logbook sites I know of (LogShare OnlineLogbook.net and one other one which escapes me at the moment) are all not only free, but also have just as many, if not MORE features than Logbook Pro.
