CHRISTOFER  Free. Easy to use. Integrates with Google maps, garmin.com and geocaching.com (and probably a lot more places that I don't use).  
(Version 2.6.2)

CHRISTOFER  For Mac users this is a good find, but for people with an iPhone/iPod touch, the new 1Password sync feature makes it a must have. I could never imagined it was possible to make a mobile password solution in such a clever way!  
(Version 2.5.10)

CHRISTOFER  Doesn't seem to be the case.

CHRISTOFER  Is it? This was posted 7 December last year(!) on the GnuPG web site, and still no new version:

"7 December 2006: Attention! There is a security hole in GnuPG versions prior to 1.4.6 and 2.0.2 respectivly. We are working hard to provide you with a current installer for version 1.4.6 as soon as possible. However, meanwhile you should try to compile GnuPG by yourself by making use of the HOWTO found in section Documentation."
