Resistive vd capacitive
I really don't understand the continual bashing of resistive screens (beyond the fact that resistive is not the Apple way).
I use both, and I far prefer the resistive.
So far the only con I have found to resistive is it can't do multitouch, fair enough, as the user interface isn't designed to take advantage of such a feature, it's not an issue.
The pros are huge. I can use it wearing gloves. If you have finger nails then you can still use it without having to angle your fingers in a way would would be a bit odd when holding the phone.
When you're not wearing gloves, the benefits starts to really appear - accuracy.
You can click on a 2mm high text link on a web page, amongst a sea of other text links, and get it 99% of the time, because you are using a narrow tapping thing like your finger nail.
Plus you can see what you are tapping right up to the point you hit it, because said fingernail is fine and narrow. Not got fingernails, well pick up anything you like from your desk. Biro lid, matchstick, car keys, anything you like, it'll work (taadaa!).
Take a capacitive one, requiring the contact of a squashy finger tip, and you'll be hard pushed to hit anything smaller than the size of a bus with any accuracy. Is it any wonder that the way to navigate "back" is such an easy gesture?
The iPhone4 might have a seriously impressive number of pixels per inch, but you can't use them to resize a webpage to tiny proportions if it has a lot of links close together, the most you can do with it is enjoy some nice font anti-aliasing.
