Started out with a Nook Simple Touch, but my eyes aren't what they used to be so I gave that to my wife & got the Simple Touch with Glowlight 4 months ago.  I am 98% happy with it- it loses a point for occasionally going back to the screensaver when I press the Glowlight button, and one point for occasional ghosting in extremely bright sunlight.  Both complaints are trivial, as the Nook's good points far outweigh the bad.
