Well, I'm cynical enough to think that there might never be a second device, so I took the plunge now. ;)
VPN: Haven't tried yet, waiting to see what the next update brings. I know people in the forums have had some success running OpenVPN, but I don't think there is any UI for it yet.
On maps: The included maps app is not great. I think the underlying map data is pretty good, certainly better than apple maps, but the UI lacks features (like the other apps). I doubt there will ever be turn-by-turn navigation, there's no street view. It's actually possible to install and use the Google maps app for android, and it at least doesn't crash.
LINE: Just tried installing and running it, seems to work perfectly fine (with caveats about running an android app in sailfish).
People say Skype is one of the android apps that works the best. I've installed it but haven't actually tried a Skype call, so I can't speak to that.
Edit: Missed the part about sandboxing. I think there has been some talk about that, at the moment there are no access controls for individual apps at all. All the parts that need to change to make that possible are open source, so hopefully someone will make it happen.
