I get almost none of my books from Borders so I have font scaling issues with almost ever book I read and it'll be much easier not to have to use a third party app to fix the bug. That said it's going to be VERY annoying have to start my ereader all the time as I'm one of those whip it out and read for 5 minutes kind of users.
