The M4 iMac is a nice computer. Apple's addition of 16GB RAM to the basic $1,299 model makes it a whole lot more appealing for the vast majority of people who just want to take the computer out of the box and plunk it on a desk and be done.

Apple has released the new iMac M4, and there are some improvements that make this a compelling first PC or upgrade option. However, there are some key reasons not to buy that you should know about before you pull the trigger.

The design remains the same, but you get a new processor and a more generous RAM offering without a price increase. Sadly, Apple is still miserly with the iMac's storage.
