The rolling release being unstable is wrong. You don't get the "dev" version of update with bugs and instability, you get a proper update, just in small increments usually.

Arch is easy enough to install. If you ever get tired of overhead, ala all the apps on the OS which you never use, just start from scratch. It's not hard to install the base, desktop envo + a browser and start from there. The cleanest desktop you can imagine and probably the resulting OS too
Difference between it and Connect? Behaves a lot like Sync to me tbf
GPS works anywhere on earth and doesn't require a cell connection, it even works in airplane mode, so you really can't get lost if you have the maps app (which you probably do)
