GNOME 3 is an easy and elegant way to use your computer. It is designed to put you in control and bring freedom to everybody. GNOME 3 is developed by the GNOME community, a diverse, international group of contributors that is supported by an independent, non-profit foundation.
Ranked in these QuestionsQuestion Ranking
Pro Clean UI
Every aspect of GNOME 3 has been crafted to fit together as a harmonious whole, so that it offers a consistent and integrated experience.
Pro Simple and easy to use
GNOME 3 has been designed to make it simple and easy to use. Press a button to view your open windows, launch applications or check if you have new messages.
Pro Powerful search
A powerful search feature lets you access all your work from one place.
Pro Keyboard friendly
It's (mostly) usable without touching a mouse, so you can keep your hands on the keyboard.
Shortcuts can be defined in the gnome setting.
There are even more shortcuts available when using the gesetting or dconf tool, e.g. switch to desktop 5 to 9.
Pro Does not get in the way
GNOME 3 lets you do the things you want without getting in the way. It won't bother you or badger you with demands, and it has been designed to help you comfortably deal with notifications.
Pro Highly customisable
Gnome Extensions offers an easy way to extend the built-in functionality.
Pro Very productive
With a clean layout and well-thought keyboard shortcuts, Gnome 3 is simply the best for people looking to be productive with their computer.
Pro Great for high dpi displays
Adjustable scaling factor makes it great for high-resolution laptops and far away TVs.
Pro Adheres to standards
Allowing for interoperability and shared technology for X Window System desktops.
Pro Easy theming
Changing the look (and feel) of Gnome Shell is easy, shell theme, icon, windows and graphical elements (gtk) individually for each user.
Mostly it's installing some packages or unpacking some archive to a themes folder and using selecting the new theme in e.g. gnome-tweak-tool.
There are a lot of really good themes on DeviantArt.
Pro Great task manager
The GNOME Task Manager is great, showing all open processes with every needed detail. For each process you can see the amount of memory and processing power that it's using, along with the process priority.
Pro Online account management
GNOME 3 integrates with your online accounts, so that all your data can be accessed from the same place.
Pro Wayland support
Gnome is the first desktop environment that uses Wayland as default instead of X server. X server is only optional currently.
Pro Fallback mode offers a classic look
For people looking for older, more classic looks, Fallback mode offers just that. Ubuntu users can have this option by installing a package called "GNOME-Session-Fallback." In the future to be released GNOME 3.8, the Fallback Mode will not be included, so this is really not a long-term solution.
Pro Touchscreen friendly
It works well with any touchscreen-enabled system, including newer laptops, even to the point of including a well-designed on-screen keyboard.
Pro Gnome-Tweak-Tool and Extensions are great
Gnome may seem bland out of the box but, the Gnome-Tweak-Tool is awesome.
The Gnome-Tweak-Tool allows for easy desktop tweaks and other control functionality, and that these features can be activated with just a click.
Pro All the major players in the Linux ecosystem have finally collated on Gnome.
Red Hat default = Gnome
Fedora default = Gnome
Debian default = Gnome
Ubuntu default = Gnome
Opensuse default = Gnome
This doesn't mean the others go away, it just means there is a colossal community and industry backing behind Gnome.
The point whether or not it being technically the best option is now off table and irrelevant. It is now the de facto standard. Like it or not.
Con Extension system is weakly integrated into the environment
Backward compatibility is not guaranteed and extensions seems like second class citizens in the GNOME environment.
Con Tightly coupled to its window manager
If you're looking to run an alternative window manager, like XMonad, you're pretty much out of luck.
Con Depends on systemd
Some people don't like systemd but it is part of most modern distros anyway.
Con Limited customization
To modify anything beyond the wallpaper requires third-party software.
Con Heavy on RAM
It is the DE that needs the biggest amount of RAM.
Con Some settings are not where the user would expect it
E.g. it is not possible to change the keyboard auto-repeat delay or rate from the usual All Setting > Keyboard like, for example, in Unity.
Con Some GUI controls are much larger than on other desktops
This is wasting screen space on non-HiDPI monitors.
Con Poor 'drag and drop into application' capability
Difficult to drag and drop a file into an open application.
Con Inconsistent desktop
As of GNOME3, some applications have ClientSideDecorations while other use normal Titlebars, this also affects usablity since both Decorations do different things if you left, right, or double click it. Same goes for Menubars. Some Apps follow the GlobalMenu in the GNOMEShell while others don't.
