The good
- Still a nice-looking, well-built computer
- Fast quad-core processors and nice IPS panels across the line
- Increased graphics performance, even in the Intel-equipped model
- 802.11ac is a nice addition if you've got a compatible router
- Fan noise, heat, and screen reflectivity are all down from pre-2012 models
The bad
21.5-inch model doesn't offer user-accessible RAM slots
No huge performance leaps from last year, which is perhaps to be expected given the maturity of the desktop market
The ugly
- SSDs and Fusion Drives are still add-ons rather than standard options, making these iMacs feel slower than they have any right to feel unless you pay for the upgrade
