The Playstation Portable's newly added web browser is a great addition to the handheld, but most importantly it can be easily exploited to streamline the process of reading text on the device.
8Bit Joystick's Jake Metcalf just wrote-up a quick guide for creating your very own PSP web start page that has been saved on a memory stick and linking to other saved web pages on the stick. His idea is to use this to read game FAQs, but you could also very easily use this system to read open-source books downloaded from sites like Project Gutenberg.
The process is a bit time consuming, but I don't think it would be that hard to master.
