iMac vs. the Macintosh

14 August 1998 - Dan Knight

The iMac is Apple's most important product rollout since the Macintosh. A column by Jim Davis on Cnet (The iMac's ancestors) reminded me how like and unlike the two computers are. Here's a comparison of features.

The iMac is about 200 times faster,* starts out with 256 times as much memory, has 10,000 times the storage space, networks at up to 400 times LocalTalk speed, and costs only about half what the original Macintosh did.

Pretty good for 14 years of computer evolution.

* A Power Mac G3/233 benchmarks at 175 times the speed of a Mac Classic, which is about 15% faster than the original Mac.
