Lab126 is not a bit shy of re-defining what already works, are they?
I recall Geekmaster (negatively) commenting on that at length.
I have a KT (still on 5.3), a stack of PW-1s and two of the four 7th generation Kindle models available.
(And a bunch of non-touch Kindles, which I am currently ignoring.)
What I am looking for now is things that have changed (by intent or otherwise) to our advantage.
A weakness of that "change for changes sake" development model.
