Here's a youtube video from a generally reliable tech review channel.
It is mostly positive for the 8in model.

And he does warn about the battery life.
Four points to consider:
1- the interface adds a Walmart button to the left of the three standard Android buttons.
2- the button takes you to a set of custom apps: Walmart, Sams, Vudu, and eBooks. (presumably a Kobo-managed site).
3- The hardware specs are identical for both except the 10in model has dual speakers. The screens are both IPS so they shouldn't be terrible.
4- Both are quite competent at surfing, video, and gaming.
Basically, anybody looking to do ebook reading on these should test out the 8in model. If it's not acceptable, the 10in will not be an improvement.
