One of the nicest feature of a capacitive touch screen that support multi-touch is the "pinch to zoom" feature that's found on devices like the Apple iPhone, the iPod touch, and even the HTC Droid Eris. There are several other smartphones that allow support pinch to zoom, but I have to admit that I was quite surprised to read that the Motorola Droid does not currently support pinch to zoom on its web browser. Why? It has a capacitive touch screen, so it's capable of multi-touch gestures. Why not support pinch to zoom?
I'm confident that the vast majority of future smartphones will incorporate a capacitive touch screen mainly for the pinch to zoom feature. This is such a handy function and I can't imagine using a smartphone that lacks that capability (well, OK - I can imagine since my current smartphone doesn't support pinch to zoom).
So, do you rely heavily on pinch to zoom when you're browsing web pages on your smartphone? This is one of the reasons why I really like to browse mobile web pages using my iPod touch. The pinch to zoom works really well and allows me to zoom right into a specific section on a web page.
