October 20, 2009: Apple goes big with its iMac redesign, introducing the first 27-inch all-in-one Mac.
The sleek, sophisticated aluminum unibody design looks so good that the iMac will remain virtually unchanged for years. As with the first Macintosh with a built-in CD-ROM drive, the iMac’s 27-inch display represents a sea change for tech. The big, beautiful screen signals that larger displays need no longer remain the domain of pampered professionals.
