It's perfectly understandable to expect to be able to read these things, but tablet PCs simply aren't designed for people to be reading them from four feet away. Arguing that you should be able to view them from that distance is like arguing that you should be able to read FFXIII Datalogs from twice the reasonable distance. I mean, if I go four feet from my PC monitor, I can see the text but it's not something I can view without feeling the strain on my eyes on some level.

All I'm saying is that there comes a point where rather than requesting a higher font size, you should consider that you are not using the platform as it was intended.
