So I switched my Linux Mint / Win7 dual install to an OpenSuse single install last weekend.

Top three things I learned:

1. Flatpak is awesome.

2. systemd-analyze is one of the coolest tools I never knew existed.

3. Gnome 3's weirdness isn't as scary as I thought. Still not my favorite, but it's growing on me.

The moral:

Switching your distro cǒuld make you think harder about how your computer works, and that's a pretty good thing.
