Well thank you all for your enthusiasm
Maybe the question is tougher than I assumed. Anyway, I called up Sony and their official response is that the font cannot be changed. Haven't looked into any hacks yet, who knows.. I did buy a SD-card, so I will put some books on it and take it with me to the store. Let me know if you're interested in an update on that.
Also, I still appreciate any comments on the price vv. future releases! Let me hear what you think of the current prices.
