If you’ve got a home network and want to keep your addressbooks synchronised,you have a bit of a problem.
Sure,you can get a subscription to Mobile Me (formerly .mac) and have the details stored online,or even transfer everything across to a Google addressbook with your google mail account.
I didn’t want any of these;the former costs money and the latter means the macs have to be connected to the net and I can’t use the mac native addressbook which is actually really nice.
The solution is Address-o-Sync.
All your macs have to be connected to the same network,with Address-o-sync open on both. Then they can chat to each other and you can synchronise your addressbooks neatly.
There are a couple of small useability issues I saw,with visually comparing addresses between the local and remote addressbook (ie,you couldn’t do it side-by-side),but on the whole it’s a really simple,lightweight solution to keeping things neat.
