My desktop machine is always on (except when I go away on vacation). I'd be happy to let it serve as a sync point. My laptop is often closed and asleep, but in that state, I don't care if it's not up to sync, as long as it takes care of that once it wakes up.

I haven't really found a good sync solution. Missing Sync bought up a company that was making a computer-to-computer sync, but that caused a nightmare of errors that I'm still not sure I've completely recovered from. Most purported fie sync (besides being file, rather than data sync) attempts seem to still poorly resolve changes on both branches. No, I don't always want to pick one vs. the other, I want the changes merged, perhaps.
