Adjustable scaling factor makes it great for high resolution laptops and far away TVs.
Pro Powerful search
A powerful search feature lets you access all your work from one place.
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 its installing some packages or unpacking some archive to a themes folder and using selecting the new theme in e.g. gnome-tweak-tool. There a lot of really good theme on deviantart.
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 Customizable with easy-to-install extensions
With the right plugin enabled in your browser (comes with Firefox by default) you can browse and install with two clicks the many Shell Extensions available from http://extensions.gnome.org. These are listed automatically based upon the version of Gnome Shell you currently have installed.
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 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 Simple, clean aesthetic
Nonintrusive and easy to overview workspace.
Pro Lightweight
Pantheon is light on system resources, giving it the advantage of being able run well on a multitude of setups.
Pro Looks amazing
Looks absolutely amazing. Very nice to use. Amazing UX.
Pro Smooth, subtle animations
Nearly everything is animated, but it's not over the top.
Pro Splitting and animations
Switching between workspaces is fluid, pulling up the workspace preview bumps up the rest of the desktop, open windows show up on the switcher along with larger icons, and everything is subtly animated. You have two windows taking each half the screen by dragging to corners.
Pro Highly modular
While built to be integrated, Pantheon is also highly modular. Shell components like the Panel, Dock, and app launcher can be swapped out with limited repercussions.
Pro Great for minimalists
Although you cannot put icons on desktop, it comes with very low number of pre-installed softwares.
Pro Perfect for chromebook
It's light and easy.
Pro Slick, smooth desktop environment
Easy to use and easy to configure, there is almost nothing that the developers did not think of to creat a top-notch user experience.
Cons
Con No taskbar by default
GNOME doesn't have a taskbar by default, and might be confusing to people migrating from Windows for that reason. It is however possible to install it through http://extensions.gnome.org.
Con Some areas are unpolished and lack features
Some aspects are still unpolished and lack features - the gnome design team works well, but seems to not be taking input from the outside world.
Con Extension system is basically unsupported
Backward compatibility is not guaranteed and extensions seems like second class citizens in the GNOME environment.
Con It tries to reinvent the wheel
It isn't a traditional interface. Very different to adjust to.
Con Poor reputation among Linux users
The whole Elementary OS project has a poor reputation among Linux users.
Con No icons on desktop
Con Too simple
Good for people who want a plug and play simple Desktop Environment. But for a multitasking / entertainment / cutting edge or Gaming Rig this is not the answer.
Con Requires tweaks to be usable
To enable things like the minimize button, status bar indicators, and what some might call "normal" desktop features, you need to tweak the system to make it usable.
Con Uses GTK
Nowadays, GTK is designed with GNOME, and only GNOME, in mind. Non-GNOME applications which attempt to utilize it suffer as a result. Pantheon is no exception.
Con Few configuration options
It is pretty bare-bones on a stock install, but further configuration options can be added through various official tweak tools.
Con Buggy
Con Not ideal for enterprise environments
As it has no set release date, and no set support and/or EOL dates, that makes it a not so good choice for enterprises managing a number of machines where such dates are important to know before hand.
Con Slow maintenance
Any significant updates come with new release, which usually takes 2-3 years. Hence gets obsolete with current software.
Con Not available for major Linux distributions
Con Limited to eOS-only
It means Pantheon won't work properly if installed on other distros. Manjaro has given up on trying since it works better on a LTS system and takes an eternity to realease a new version or add security updates. On Arch, Pantheon also doesn't work properly. People are trying it on Fedora, not sure how it works now. If you want to use Pantheon, better get to eOS.
Con Looks and feels like a Mac
Which may turn quite a few people off with the aesthetics, of course for some people, this is a pro.
