How the dev community is talking about multi-touch and iPhone gestures.
Just an FYI forward:

The iPhone Ajax buzz continues. Joe Hewitt (Firebug) writes about the
new multi-touch events that he hopes show up:
I've read lots of people, while arguing for why iPhone web apps are
lame, assert that web apps won't be able to take advantage of the
iPhone's multi-touch screen. This is nonsense. I completely expect
Apple to have extended Safari with new DOM events that allow any web
page can respond to the variety of gestures the user can make with the
touch screen and accelerometer.
Won't it be fun to handle "ontilt" for when the user turns the phone
from portrait to landscape mode, or "onpinch" for when the user pinches
the page with multi-touch? Should the "onscroll" event include details
about how fast the user dragged her finger, to indicate the speed to
scroll? Developers are going to have a field day with this stuff. I am
sure Apple has thought these things through and won't let us down.
Robert Cringely has his opinion on iPhone and Ajax:
The iPhone absolutely needs AJAX applications for the phone to be a
success on AT&T's EDGE network. By pushing more functional logic into
the browser, the bandwidth consumed per http round-trip is
significantly reduced, making the phone apps faster and helping to
justify that big price tag. The problem with this is that AJAX apps
don't always work the same (or at all) on every browser. The iPhone has
real browser support, which is good, but remember AJAX is based on
Developers are typically forced to hand-code different versions of
their AJAX apps for different browsers. With the AJAX economy dictating
that browsers with big market share like IE and Firefox get most of the
effort, that leaves Safari as a second-class browser and, potentially,
a liability for the iPhone.
Bandwidth is one piece of the puzzle, but what about the cost of
connections? If a connection across the network is painful (and I think
it is!) then Ajax isn't going to necessarily help, and can in fact
become a hinderance if abused. Will the apps be so good to make you
frustrated at the EDGE?
To get testing applications you can download iPhoney and simulate away.
