Yeah, it would have been nice to have that option. Or heck, even an ability to change the frequency of refreshes more than simply on or off (though just having that would be nice). Say from every page up to every 10 pages (I don't find the ghosting bad at all on the current amount, and might not even with a few extra page turns before a refresh).
Of course, if wishes were fishes I'd be asking for allowing me to set a device name and getting the shelves to work right with microSD content, oh and having access to the 750MB of reserved storage space for side loaded content.
Maybe also customizing the home screen with what I want on it.
