1 – Since Leopard time-stamps differently, syncing iPhone between Leopard + Tiger Macs means constant “replacement” of same files.

2 – 365 “old” calendar events get deleted; 365 “new” ones replace them. Same with 1GB video files. “Old” one is deleted; “new” one gets written.

3 – “Calendars” and “subscriptions” are also different between Leopard and Tiger, causing data loss when you sync.

4 – Choices: Update all Macs to Leopard (even though CS3 is wonky in it). Or sync iPhone only to one Mac (home OR office, not both). Or buy PC?

This would seem to end things. But then JZ pipes up:

(5) – : @zeldman – Seems to me that you need .Mac. Sync your phone to just one computer and then sync both computers to .Mac.

So one wearily continues:

6 – .Mac sync fails between Leopard + Tiger due to changes Apple made between OSes. .Mac freezes instead of syncing. .Mac useless now.

7 – Obviously Apple requires you to “upgrade” all your Macs to the same OS version, otherwise everything (including iPhone) is half-broken.

8 – It’s the kind of stuff that’s supposed to happen to the John Hodgman (PC) character, not the Justin Long (Mac) guy.

Rimshot!
