Yeah, I'm notoriously unpicky about such things, too... Meeks is an amazing artist and probably the exact opposite of me when it comes to visual processing.

Question on your Droid: which font style were you using? Neither's markedly bigger than the other but when I tested it on my Android-powered LG phone, I found that serif felt small and hard to read vertically but the san serif one was pretty comfortable vertical, and I wonder if your experiences are similar or different.
