I have the black 55g at work, and the white / grey variable-silent at home. For overall typing "feel" and that delicious Topre "thock", the 55g takes it all day long. However, unless you're a perfect touch typist, be prepared to have to squint for the black on black letters in low-light conditions. That's why I'm running the black at work (always brightly lit), and the white at home (sometimes low-light conditions). Even as a touch-typist, there's probably a handful of symbols that you don't have down pat.
buybuybuyhaha, no matter how good you touch type the first set of blanks you get will prove how little you actually know your keyboard. THEN you buckle down and learn all the symbols you didn't even realize you didn't know haha.
buybuybuyHey I'm thinking of getting a black RF for work as well which is well lit. Are they still difficult to read or is it a non-issue (in a well-lit work environment)?
