I always wanted to have one true contact list, and share it between my desktop and a mobile device. Paper phone books are much easier to enter and retrive contacts, to be honest, but they are not backup- or sync-friendly, and after months they get a mess and need to be started over. On the other hand, I was never really able to really sync my Evolution contact list with a PDA, a cell phone or even my N800. There’s always an issue: poor syncronization software, mobile device can’t handle many contacts, different applications use different parts of the vCard specification and so on.
So, I guess this is sort of a Dear Lazy Web post. I’d like to know your successful stories: which devices and software did you use to keep the same contact list in the desktop computer and in the mobile device (PDA/cell phone etc.)?
