Hi,
I have the Touch Lux with backlight. Wouldn't this be a better option? I just can't imagine how people read without that option. I usually read in the late evening and a external light source would be annoying for my wife when she want's to sleep...
The Pocketbook Touch Lux also has a higher resolution then both Kobo Mini and Basic Touch (PB 624) as well as backlight.
Both Touch Lux and Basic Touch have a 6 inch screen and not 5 inch as the Kobo Mini. In case you want the smaller size try the Pocketbook Mini (5 inch, no backlight) with the same resolution as the Kobo Mini I believe.
Check out their website

My opinion on the Pocketbooks in general is very positive, although there could be some improvements.
