The yellow tint compared to the blue should be softer & warmer on the eyes than the colder, harsher blue of the older ereaders like the Glo. It is supposed to be cream though, not very yellow, and in some cases it can look too brown/yellow instead of a cream/yellow. There are also just going to be some people who actually prefer the bluish light. Personally, it was one of the reasons I was never tempted by the Glo when looking at Kobo ereaders.
