I found the Nook extremely frustrating and had trouble getting the feel for it. It bothered my that even with effort/focus, I couldn't seem to get it to work smoothly. Although, as the sales clerk pointed out, once the book open the touchscreen isn't needed to read. |

hi,
you realize that there are a few different "input" methods that are being used on screens?
-1-
resistive: there is a layer on the screen that needs to be physically pressed. it works with fingernails, stylusses, spoons, forks... :-) everything that has a point and can be used to press on the screen. Also works with plastic styli
-2-
capacitative: iphone, nook and other devices use this. it is more sensitive (often) but it needs an electrical capacitance (sp??) to work. therfore it will work with your skin, but not with your nail. it does not need to feel "heat" this will not work with a plastic stylus, and will not work with you wearing a glove. there are special styli with an aluminium sponge on the end which will work.
-3-
active digitizer: the most accurate method, will only work with special styli which have a coil and some circuitry inside. nails and hands will not work. therfor the only technology (now) that lets you write on a screen like on paper : it will not be disturbed by puttting a part of your hand on the screen, which you are likely to do when writing on a tablet pc.
furthermore there are combinations of the above, of which a very good one is a -3- and -2- combination which switches between "touching"and "writing"mode.
===
you see why ther are differences in "how the screen works". furhtermore the speed and the software of the device have a lot to do with it.
the iphone is in my opinion now the most "responsive" device, but as explained above, it will not work with nails
