8" widescreen doesn't exist I'm affraid. 7" has a 16/9 resolution, where 8" is 4/3.
this is a new model they have at cartft it's basically the same as the CT700-H but with transflective instead of TMR, a bit to expensive if you ask me.
Anyway My Xenarc 700tsv is starting to back out on me, but I think I'm going for the CT700-H
