Fair enough, MEP. .Mac may not be for everyone (it's worth it for calendar and bookmark sync'ing for me on a bunch of machines, but I may be a rare case).

I'm only suggesting *some* sort of sync. I think when talking about a productivity tool like this, it's really not a second-class feature. Having the lists of things I need to do at my finger tips in all my actionable contexts is really the whole point of GTD. It's exactly why people I know are (as David Allen himself describes) using note-cards instead of an electronic system. Notecards go everywhere with you.

A GTD system stuck on my laptop is fine for all my @laptop tasks, and rather useless for the rest.

Whether the sync is done through .Mac or through some custom setup is totally up to Omni, I'm not wedded to .Mac, but I think it'd be a natural and Mac-like solution, for better or for worse.
