i agree, but did you notice that monaco 9 point without anti-aliasing in this article looks very similar? which seems like good news to me, because if schumacher disappears then there's something to fall back to...
True, monaco9 looks a lot like clean12. However, I use a 13point version for coding. It's a little taller and for that reason, in my opinion, clearer. If schumacher disappears, I should look for monaco 10pts, as I can't find it on my linux box...
