Making the Most

[rctlr]

I have
Mac Mini with SL
Mac Pro with SL
MBP with ML
iPhone 5 with iOS 6.0.1

I have calandars and email synced between all the devices using iCloud.
I have bookmarks synched between MBP and iPhone using iCloud, and between MBP, Mac Mini and Mac Pro via Xmarks.

I have a problem with Contacts.
Synching between MBP and iPhone 5 via iCloud is just fine however I cannot sync to SL machines.

I know of two choices:
- Use Google. I've taken some time moving out of the googlesphere over the past 12 months - moving back in is easy, but I'm not sure I want to. Moving just contacts would just be the thin wedge to move back, and ditch iCloud for PDA functions.
- Use Fruux for contacts, I've played but feel a little "dirty" using them as I do not know how long they will last.

Are there any solutions anyone has found for this?
