But when the data transfer rate become higher, the bandwidth cost should be considered.

  • I joined Microsoft in 1993 when it was hitting its stride. It had recently released Windows 3.1 and Windows NT, setting itself on the path of more than a decade of dominance in the PC operating system market, and the many other markets that flow from it.

    One day it just hit me — I should quit.
