 The ThinkPad, a premium machine which then cost US$4350, included a 25 MHz Intel 80486SL processor, a 10.4-inch active matrix display, removable 120 MB hard drive, 4 MB RAM (expandable to 16 MB) and a TrackPoint II pointing device.The striking black design by noted designer Richard Sapper made the ThinkPad an immediate hit with the digerati, and the cool factor of the ThinkPad brought back some of the cachet to the IBM brand that was lost in the PC wars of the 1980s.Instrumental to this popular resurgence was the 1997 chess match between IBM's chess-playing computer system Deep Blue and reigning world chess champion Garry Kasparov.
