I like how it handles contact info, but since it doesn't include any printing (to envelopes, lists etc) functionality nor Groups, I had to revert back to Address Book.

Cool little app. I am not totally enamored of the UI behavior; I would like to be able to either [1] adjust (increase) the delay before the full address card pops out from the list, or [2] be able to pop the card out from the list with a mouse-click instead of that replacing the list with the full card.

For my purposes, CoBook has become a lot more valuable since it has acquired phone-dialing capacity (via Dialectic or FaceTime). For some reason, Apple has never gotten the point about this feature: if you use Address Book to store your phone numbers, shouldn’t you also be able to use it to dial your numbers? CoBook is a very useful substitute for this lack. (Note: if you want to use this feature on a Mac running Lion you can’t use Apple’s own USB modem, since its driver is 32-bit only, but you can pick up a third-party one cheaply). My only complaint is that the claim on the MU page “ It synchronizes with Mac OS X Address Book and other devices via iCloud“ remains as misleading as ever, since it wrongly gives the impression that CoBook is an iCloud client. I think a disclaimer should be added to the product description. In fact, a iCloud client for contacts is greatly needed for those of us who have Macs that can’t be upgraded to Lion or who depend on software that runs by Rosetta. At the moment, the only available one is SOHO Organizer, which is outrageously expensive and, i. m. h. o., has a very clunky interface because it tries to be too many things at once. If the developer could turn CoBook into a genuine iCloud client, he would transform a very good program into a great one, which many many people would find indispensible.

I started using Cobook about five weeks ago. I've been delighted with it. It took a bit (not much) of getting used to. Now I'd struggle to do without it. My outstanding request was to enable me to use it to dial phone numbers with Phone Valet. I've now discovered that I can do this via Dialectic. Great product and looking forward to seeing where it goes next. For some reason, I can't award 5 stars for value and stability. I would.

I love this app. I used to just HATE using address book until this came out. I used to sync all with Google but this is working so well that I gave up Google contacts and now use iCloud for this app to work. Eliminates all the double names I used to get. For me this is a must have app now. A BIG THANX for this app!!!

Something like "service error"?
