Does anyone know if the shelving/collections issue of SD card stored books has been fixed in the software release for the Glow?

I wonder what would happen if you up a screen protector on top of the screen. I always use a screen protector. Wonder how much more it would effect the text.

Can you name one? All the readers I'm familiar with have an outer plastic screen over the glass substrate of the eInk display; the glass substrate is much too fragile to be exposed.

Here's a take down video showing disassembly of a K3: http://www.powerbookmedic.com/manual.php?id=116 There is clearly nothing between the eink module and the front cover opening. (and we'll just ignore that he calls it an "LCD"). But if you mean that the front of the of the module is made of plastic and not glass, I'll take your word for it. I was referring to the fact of it being a single exposed, expensive component. I'm not sure why I said "glass surface" and not just "surface." I had no idea what the material is. Perhaps seen I've seen so many cracked, I assumed the surface was was glass. |

This new layer BN is adding to the surface has me a little worried if indeed it is more sensitive than the regular surface (whatever material that is - I have no clue either). |

No. Same behavior. When you eject the SD card and reinsert it you lose everything you shelved on the SD card. It does retain your place in the books on the SD card though.

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. |

The ir emitters can use A LOT less power, like orders of magnitude less, as they only need to be detectable to a sensor a few inches away, as opposed to having to be not only detectable, but comfortable, to a human eye several feet away, after being reflected off another surface. But for the sake of discussion, even if we assume that they used exactly the SAME power as the glow light, then now we are talking about DOUBLING the consumption. |

Yup as mentioned the Infrared LEDs use a lot less power. I've seen IR LEDs that use on the order of microwatts of power per LED. If I had to wager a guess the total power budget of the entire infrared touch screen, both emitters, receptors and the signal processor probably is less than 10 miliwatts total. If I were to take a guess as to the total power budget of the glowlight LEDs, it is probably in the range of 50-200mw between minimum and maximum brightness (LED dimming also is not a linear change in terms of power consumption reduction and brightness level, an LED outputting 20% of its maximum luminance might be consuming only 30-50% of the power at maximum instead of 20%).

I'd like to know too. I'd really rather place an aftermarket, replaceable screen protector on its screen.
