So I'd be surprised if it isn't a significant hit.

but doesn't the NST have LED lights on all the time anyway? i was under the impression that the "touch" was implemented via a grid of LED lights just above screen level, which will be on as long as you are reading (they turn off when the screen saver comes on).
i won't even hazard a guess as to how much power the infrared LEDs drain compared to the glowlight LEDs, but the existing lights don't seem to cost all that much power.
