@mojos, thanks for the karma!
I hope you enjoy your Kobo!</inside information>
For 30-50 books a year (a little less than a book a week on average) I would consider an ereader worth it.
You should definitely take a look at the
Kobo subforum, where the hacks and customizations and stuff lives.
I'll probably bow out now, as I don't really know a lot about Kobos.
