Apple iMac 21.5-inch (Thunderbolt)
Performance, as a rule, jumps up every generation or so, and the Apple iMac 21.5-inch (Thunderbolt) ($1,199 list) is no exception. With a second-generation Intel Core i5 processor and DX11-compatible AMD Radeon HD 6750M graphics, the newest iMac adds class-leading performance to the already iconic iMac chassis. The newest, hottest Thunderbolt interface is the gravy. If you’re a Mac user upgrading a 2005 Mac, or if you’re new to the Mac fold, the entry-level iMac is a compelling choice that will keep you happy for the next 5 to 7 years.
Design and Features
On the outside, the new iMac 21.5-inch (Thunderbolt) is identical to the previous Apple iMac 21.5-inch (Core i3) ($1,199 list, 4 stars), including the same glass-covered 21.5-inch 1080p panel, wireless keyboard and mouse, and even the same row of I/O ports in the back. The one notable exception is that the older desktop’s mini DisplayPort has been replaced with a Thunderbolt port. Even though they look physically identical, the Thunderbolt port is capable of dual-channel 10Gbps communication, much faster than USB 2.0, USB 3.0, FireWire, or eSATA. You can hook up many more devices to the Thunderbolt port as well: The interface can daisy chain devices together so multiple devices (like hard drives, monitors, printers, and input devices) can all use the same port on the iMac. The new iMacs come with a choice of the Apple Magic Mouse or Magic TrackPad for the same price. Our test unit came with the mouse.
