Been reading the Prags new C# testing book. It's good. But I'm finding it hard to read. They say it's designed for onscreen reading, but, well - it's not. The type face is a serif*, and it ascendent and descendent strokes are too narrow. They appear gray and don't contrast strongly enough with the background (possibly this font was anti-aliased). The code samples have pretty colours, but are in tiny-text. Overall, the book looks slightly like a fax. I'll be buying a print copy next time. Sorry trees. Yes, everyone does this, but please, consider using a sans-serif font onscreen....
