Yes, but there is, as I have read in forums, a "difficulty" with firmware update. You cannot install any firmware (like this presented by Booxtor - yet another "official" Onyx distributor), but you have to wait for firmware release by
www.onyx-boox.com.
If you consider e-reader with IVONA 4 text to speach engine (which is said to be very good), check what the situation with firmware update is. Maybe there is no real problem and special editions of firmware for those readers are released with no or only small delay...
Just to avoid any misunderstanding, I do not say, do not buy it there. If you expect to use TTS, Onyx with IVONA is probably worth considering, but there might be the "cost" of less flexibility of firmware updates...
