I much prefer resistive screens due to the ability to accurately click on small links (and desktop-ported UI elements) with my fingernail. The resistive input on the n900 is remarkable for allowing easy swipe-scrolling using only fleshy parts of the finger and thumb. In addition accidental registration on a resistive screen is rare.

I find it difficult to click small links on capacitive displays, partly due to my finger covering the small link I am trying to press (intrinsic problem when requiring fleshy bits for input). In addition, accuracy/calibration issues near the edges of capacitive screens are frustrating. In addition lack of registration (due to mildly dry skin?) can be irritating.
