Other aspects of GNOME 3 that took some getting used to include: the applications layout and being able to locate applications easily using the built-in search feature. I've also found myself intrigued by the renovated Workspace options offered by GNOME 3. Lastly, the Activities overview mode is another great way to manage open applications and other windows. This seems to be the new alternative to offering default options such as the minimize option; at least without using the GNOME Tweak tool mentioned above.
GNOME desktop unification will rely heavily on the applications that are well-integrated into the new GNOME experience. At this point, many applications aren't there yet. Granted, some software titles like Firefox can be themed to better fit into the new GNOME desktop. But for the most part, applications on the GNOME desktop aren't going to blend as well as we might like. In the future, I hope we'll see greater application integration.
If applications start to embrace the GNOME environment, it could mean amazing things for the GNOME desktop in the future. As things stand now, GNOME is pushing the envelope and I think they're off to a good start. I'm still not convinced GNOME focusing on tablets, as well as the desktop, is the best way forward though. Then again, we just started the new year and anything is possible. Perhaps it'll be GNOME that manages to bridge tablets and desktops before anyone else.
Speaking for myself, I'll stick with the Cinnamon desktop as it provides me with a work flow that both meets my needs, and doesn't require me to alter my muscle memory. In the future however, perhaps GNOME will grow on me permanently.
