Disclaimer: I don't have much experience with capacitive screens.

I don't know what the big deal about capacitive screens is. I've used the 5800 as my main phone for the past few months and I've only used the stylus when I first got it just to try it out. I haven't had any technical issues using the interface with my fingers. There are some design issues to S60 5th Edition and some design issues with the phone hardware design itself that make it a pain to use sometimes but that's a whole other topic.

Bottom line: I use the 5800 resistive screen with my finger, no stylus.

Another thought about capacitive... correct me if I'm mistaken but you can't use screen covers with capacitive screens. I use a screen cover with my 5800.
