As I blog from Ubuntu Linux on my Dell PC, I'm thrilled to be free of Windows Vista and Windows XP, and all of the security headaches I used to endure.
Microsoft deserves credit for pioneering the world of low-cost microprocessor software in the late 1980s and the early 1990s. Too many of us forget how expensive (and complex) life was during the mainframe, mini-computer and Unix ages. With Windows and open PC hardware came customer choice, lower-cost applications and competition in the software market.
That healthy competition nearly died in the mid-1990s as Windows became too dominant on the desktop. But Linux and Mac OS X have restored competition on the desktop.
During most days, I proudly say "I'm a Mac" because I continue to use my MacBook Pro for many applications. However, when I say "I'm a PC," the phrase doesn't include Windows or Microsoft. Instead, my PC proudly runs Ubuntu Linux.
