Anyone done anything with these recently? Any good sites? A nice "design how-to" aimed at the engineer would be extra-special cool, particularly if there's information about tradeoffs in cost, resolution, robustness and longevity.

Do you need to implement control loops in software? "Applied Control Theory for Embedded Systems" was written for you. See details at
I believe Microchip has a touchscreen Appnote. There is a Tshark touchscreen controller with microchip code availble.

Just repeating this in another thread.
Yes, we can certainly get it going. We did a 4"x3" (approx) VGA sized mono-LCD w/ resistive touch for around $5 each, but minimum of 10K glass. Controllers and other electronics can be less, but not the glass. BTW, no manufacturers or distributors stock them, even for standard sizes.
In addition, single chip controller can usually handle upto VGA resolution. Resistive touch is for single touch, not multi-touch as in cell- phones.
