Today, Apple announced changes to its iMac product line, with significant upgrades in the 27-inch model, a move to SSDs in the 21.5-inch model, and more performance at lower prices for the iMac Pro.

The 27-inch iMac still has a 5K display, and its chassis is the same. Those hoping for smaller bezels will be disappointed. That said, Apple is bringing TrueTone to this display, and it's offering the same NanoTexture tech we've seen in the company's Pro Display XDR as a $500 upgrade.
