The iPad 4 is a minor upgrade over the iPad 3 - one that hasn't been made obsolete, as of January 2018, in terms of official Apple repairs, but it has been essentially retired, as it cannot update its software to iOS 11. With that being said, it may be still worth purchasing.
Before we venture forward in this review, you should note that if you plan on buying a used cellular iPad 4, then the device will likely be unlocked. This means as long as you have the necessary SIM card, you'll be able to tether your iPad 3 with carriers that support the device. For more information on what plans you should consider for your iPad 4, you should refer to our tablet plan comparison tool.
In reference to the design of the iPad 4, the build doesn't deviate from the iPad 3. The body of the iPad 4 is premium-appearing, featuring a curvy aluminum back and glass front. However, it remains a little heavy and thick, like the iPad 3. Additionally, the iPad 4 features 4G connection support and three storage options - 16GB, 32GB, and 64GB.
And what of the display? The fourth-generation iPad features a 9.7" diagonal display with a default resolution of 2,048x1,536, creating a pixel density of 264ppi, which is four times the pixel density of the iPad 2.

Processor and RAM-wise, the iPad 4 is equipped with the 32-bit Apple dual-core A6X CPU and 1GB of RAM. For the record, the A6X processor is roughly twice as fast as the A5X. Though it didn't mean a lot initially in terms of everyday usage, with the iOS updates, it makes a considerable difference.
In concerns to the camera, the iPad 4 features a 5-megapixel rear-facing camera that is capable of shooting crisp 1080p videos and photos. There is also a 720p HD front-facing videophone camera that is for FaceTime.
Finally, there is the battery life to consider. The battery life of the iPad 4 is somewhat of an improvement over the life of the iPad 3, lasting a little over 10 hours thanks to the rechargeable lithium-ion polymer 11,560 mAh battery.
So is the iPad 4 worth your dollar? Yes, if you don't mind a minor upgrade from the iPad 3, even though it is a bit more expensive by comparison. However, you will miss out on the iOS 11 update, which will leave your system vulnerable to exploits and other security issues if you are not careful.
