IBM Selectric II for me, please!
I learned to type on an Olympia manual (a behemoth), and after moving up in the class was allowed the Selectric I. But, joy of joys, in senior-high business class I discovered the Selectric II. After graduation, I worked at the Courts here in St. Louis County, and our brand-spanking new computer system had IBM keyboards. Oh, how I LOVE that click-clack sound.
My speed is always at its best on an IBM.
I still take notes in Gregg shorthand at work, the kids think I am WEIRD. I do believe they think I made up my own language.
