Pro Great performance for creative professionals

Pro Great multitasking performance
You can customize the RAM to be up to 64GB. That can be an overkill for most people's needs. 16GB should be enough for most people for even the most resource-heavy tasks.
With 16GB of memory and a 7th generation Intel Core i5, the iMac has more than enough horsepower for daily tasks. It can handle almost everything you throw at it without any issues. Browsing with 20+ tabs open for example does not strain this PC at all.
Pro The speakers offer great sound quality
Especially bass-heavy tracks sound rich and full. The volume is great as well.
Pro Great for video editing
The 5K display lets you do full resolution 4K video editing and still have all your toolbars and sliders on the screen.
Pro Can be used as a monitor
The HDMI output on the back of the computer can also be used as an input. This allows to connect a second computer or a gaming console to this all-in-one PC and use it as a monitor.
Pro Usable in bright light conditions
Because of the brightness of the display and the fact that it’s a matte one makes it easy to see the picture even in bright light conditions.
Pro Touch support
The screen supports touch inputs so you can use all the tap and swipe commands found in the Windows 10 operating system.
Pro Sleek design
This is one of the best looking PCs in its price range. Its chassis is slim and compact, measuring only 1.6 inches in the thickest part while the display has a border-less design that makes it look larger than it actually is.
Pro Great color reproduction
The display can reproduce 112 % of the sRGB gamut and has a Delta-E accuracy of 0.08. This means that the screen can be used for photo editing and it is on par with other more expensive all-in-one computer displays.
Pro The camera can be hidden inside the PC
The camera can be hidden away inside the PC. Not only that gives a cleaner look, it also adds privacy if you are afraid that someone will spy on you.
Cons
Con Ports are in an awkward position
All the ports are in the back of the PC, which makes it annoying to insert USB/Ethernet cables since you have to either get up, or turn the screen around to insert a cable.
Con Can't use the mouse when it's charging
The Lightning cable has to be plugged into the bottom of the mouse. This makes it unusable while charging.
Con No touchscreen variant
There's no touchscreen variant for the Apple iMac.
Con Awkwardly placed USB ports
None of the four USB ports are easy to reach as two of them are located on the back of the unit while another two are located on the sides of the pop-out camera. This means that you have to deal with privacy concerns if you want to use these.
Con No USB-C ports
There are only USB-A ports but no USB-C ports. While not a big deal for now, USB-C is slowly replacing the older USB standard and the lack of it may become noticeable.
Con Odd webcam placement
Instead of placing the webcam on top of the monitor Lenovo has placed it under it. This position means you can't view your display without looking like you're gazing away somewhere in the distance.
Con Noisy fan
Despite the fact that the computer uses low-voltage processors that are relatively cool the cooling fan runs frequently and generates a noticeable white noise.
Con Low resolution display
The 23 inch display has a full-HD resolution. Full-HD is already a minimum today while other models are equipped with 4K or at least Quad HD resolution.
