i just discovered Groupoffice and it is really a nice product
. What i'm missing is the possibility to buy just the Sync module.
For company use, the price of the Pro version is really a good deal - but just for private use it is a bunch of money when you are satisfied with the community version, but missing the possibility to sync the phone / PDA with it makes it not so useful.
What about selling just the "Sync" feature for us private guys who don't need the project stuff, address lists and so on?
