I got a book mark out of one of them yesterday.
Just phasing out the Kindle as (a) I've ceased to use Amazon and (b) it doesn't work very well [1]. Now have aKobo Aura HD and we'll see how well that goes.
[1] Has over 3GB of memory but is now unusably slow (except on page turns) having only used 1GB of it. Also has a failing page button.
