I have the version before the Touch -- the one where they added wifi. I'd love to hack it just enough to get fixed width code examples to (mostly) fit the display width. Or, better yet, to get it to support a landscape display of ePub books (for the same reason). I don't suppose someone's already done something along these lines? (Just asking in case happenstance brings a knowledgeable reader past this comment.)
The Wifi version is also hackable in the same way. You might want to google "Kobo wifi hacks" and start looking around. Unfortunately, it's pretty early in the scene and developers are still working to figure stuff out. I'm not sure there are yet any workable apps written for these devices.
Unfortunately, my initial editing of an individual ePub title to adjust the font used for was not accepted; I'll be exploring why, as I was trivially modifying some apparently successful instructions for adding custom fonts to e.g. support non-Roman language characters (Cyrillic, Chinese).
