I have had my Irex 800SG for about six months. The only objection I had was the lack of a filing system for books. The latest upgrade fixed that.
It satisfies all of my requirements. I have an excellent file converter for PDF to EPUB. I never save PDF books.
I have 4 GB memory card and it seems to be more than enough for me.
I have only one problem; the damned thing stopped working. I can't find the correct place to get a service ticket. This location "thttp://support.irexnet.com/" only seems to support the Iliad 1000 devices. It does not even have the DR800 model numbers.
AND - After registering and submitting a support ticket - the ticket does not seem to be accepted.
Does anyone have any suggestions?
