As a non-English speaker (and above all reader
) I have some issues with the fonts in T1. Both T1 and T3 (on T1 I have the cover with light from Sony, on T3 I have the "magnetic" cover coming into the packet) are super. Too bad they are not protected against water or sand, and that they have no illumination.
I did not jailbreak them, no upgraded (to Kobo).
