Hi Croker!
I assume you are in the UK somewhere, so wonder if you have got access to buying from the Sony Connect bookstore in the US? I agree with you, I haven't found anything really of interest yet on Waterstones, but I think the quality of Sony Connect is much better (of course what is better is subjective I know

. But I on and off check out what is happening on NYT's book section and their reviews, and it often happens the books reviewed there get published a couple of weeks later on Connect. So for quality books (sorry I know I mean the books I consider quality books

I for sure think Connect is the best place.
