[IBM](/wiki/IBM "IBM")'s 1984 introduction of the AT was seen as an unusual move for the company, which typically waited for competitors to release new products before producing its own models. At $4,000–6,000, it was only slightly more expensive than considerably slower IBM models. The announcement surprised rival executives, who admitted that matching IBM's prices would be difficult. No major competitor showed a comparable computer at [COMDEX](/wiki/COMDEX "COMDEX") Las Vegas that year.
