It was also significantly less expensive the LC III with an 80 MB hard disk was priced at US$1,349 at introduction, $700 less than the LC II. It replaced the commercially successful Macintosh LC II in Apple's lineup of mid-class computers, and was significantly faster, with MacWorld Magazine benchmarks showing 2x performance in all major categories - CPU, disk, video and maths.
