The Mac is great because it inspires people to write programs like JeepSafari.
This is a little program that does one little thing: it takes the bookmarks from your Safari browser and syncs them, using your .Mac account as the conduit, with your browsers on all of your others computers.
In other words, it makes it possible to have one set of bookmarks, and to keep them in sync on your office and home computers: when you add a bookmark at the office, it gets synced up with your browser at home.
It doesn’t try and be something more than it should be, and it doesn’t try to establish its greatness through showmanship. It just works.
The spirit of the program is the best union of the pragmatism of the Unix world with the flair of the Mac world.
