I feel the need to add a comment here since the remarks seem very old.

I bought LogTen at 4.7 because I had tried v2 and 3 demos and didn't really like what I saw. However with this version and the SQL database I think performance and features are great. I've since purchased the iPhone addon app and I log all my flights right there at work. When I get home I just sync it up with my mac and print out the pages from time to time. It's a great timesaver for me logging 80-90 hours a month, but for casual users it's probably overkill. If you're a pro however and using a mac this is a solution I would recommend.
