wintel
     
         A term describing any computer
        {platform} consisting of some version of {Microsoft Windows}
        running on an {Intel 80x86} processor or compatible.
     
        Despite the dominance of the wintel platform, in its many
        forms, from {MS-DOS} on an {Intel 8088} to {Windows 2000} on a
        {Pentium II Xeon}, there are many "non-wintel" {platforms} in
        use.  These include {Acorn}, {Amiga}, {Apple}, {ARM}, {Atari},
        {A\Box}, {Be}, {Network Computer}, {OS/2}, {PowerPC}, {Psion},
        {Linux} and all other {Unix} systems.
