Kindle doesn't allow to change fonts officially but it can be done with jailbreaking. The possibility is there and we only need publishers and authors to nudge Amazon and others to provide more features. If Rowling could exert such influence that would be great.
The problem is that authors usually don't want to give more options to readers, instead they want to force exact format they personally like. It is not reasonable because then the pdf is the ultimate format for every reader. Due to this conflict the development of e-formats is hampered.
