Why should AT&T take OS/2 seriously as a threat to Unix? That question could only be asked by a European: in Japan, OS/2 is making big inroads into the office where Unix has scarcely made a start, and in the US, Unix for business is still largely a heretical concept, while the idea, now widespread in Europe, that OS/2 on the PS/2 should be regarded as IBM’s intelligent terminal successor to the dumb 3270 and of very little interest to non-370 users, is not given wide currency, and over there, large numbers of MS-DOS users do expect to go OS/2.
