Type All-in-one
Processor Intel Core 2
Memory 2 GB – 8 GB
Storage 320 GB – 1 TB
Screen 20″
Weight 9.1 kg What reviewers say Macworld found the performance improved but preferred the larger model's screen and value; its 20-inch panel shifted colour and contrast off-centre. ASCII's separate hands-on tests found the shared graphics trailed an older model with dedicated graphics, while the memory expansion offered useful headroom for creative applications.
