Hi Anthony,
I am new to Daylite and I have Daylite Server and Daylite Touch to sync with my iPhone, although I've had to compromise my workflow in order to get eveything to work together (and i'm not there yet).
1. As the server is loaded on my mac, I loose real time updates and i have to push my iPhone to sync.
2. I use a number of iCal calendars that sync with iCloud and therefore can not use these calendars with Daylite, so i have set up a 'daylite' calendar 'on my mac' although at this time i am just using it for logging telephone appointments/conversations as I can't bring myself to loose iCloud support just yet.
3. Also as my contacts are in iCloud, i have to keep a seperate Daylite contacts list which is also a heavy compromise.
4. Daylite is very good BUT be warned you will need to invest lots of time to get it right for you and your workflow will be compromised before it improves. prepare youself for lots of long nights watching youtube tutorials!!
Daylite telephony integration has been a nightmare to set up...although when I get there I think it will rock!
I hoep this helps a bit...
Simon
