No fingerprints what so ever on any of the eInk touchscreens I have or have had! They are matte, and with IR they don't actually require you to touch the screen most fo the time. An "almost-touch" is enough to turn pages on for example the Sony PRS devices.
My LCD devices, like the Nok Tablet, though... OMG, that thing is a finger-print magnet! I try to always keep a soft fibre cloth nearby.
