And for a guy who didn't type, not one spelling error, not one miskeyed letter, perfect alignment and centering. Not bad.
The line breaks are actually more telling here than the font, the superscript, or the lack of any typographical errors.
I work for Microsoft, and have supported Microsoft Office for a long time. If you type that memo in Word 2003, under default settings with the same font, the linse auto-wrap EXACTLY like the *ahem* 1970's memo. The chances of that actually happening, for every line, on a variable type font as opposed to monospace, are exactly nil.
They might as well have written the damned thing in crayon.
