I reckon, reading the posts, that if you've already got a kindle
(stuck with one ?

) - you aren't going to say you want a touchscreen, & if you've a Sony. Nook, Kobo etc... ( yes, you deserve one

) you aint going to say you would rather have a keyboard !
And incidentally, I've never yet actually spotted a finger blodge on my screen, which means I'm either a mucky slut, or I'm doing something right.
( Course, it is possible I might just have eyesight as of Superman, and just see through the deposited murk and muck

)
