Unless that has changed, but downloading the SDK is free. If you want to run
your apps in an iP*, you need to pay the 99$ yearly fee to get the right
certificates. As long as you're happy running in the simulator, you should be
fine, AFAIK.

Thanks for the info - I was interested in iPad apps, but put off by the $99
just to download and look over the SDK.
A web app sounds better - you wouldn't have to write a different one for
every smartphone.

I started playing with iPhone/iTouch/iPad web apps just last week.
http://developer.apple.com/safari/library/navigation/
index.html#section=Resource%20Typestopic=Coding%20How-Tos
Apple has made it incredibly easy to create a web app that runs exactly
like a native app on these devices.
Of course, perl is a perfect server side language to power these apps,
and BBEdit and Perl on a Mac make the perfect IDE to create these web
apps.
While poking around there I also found out that Safari on the Mac OS
also provides some big enhancements for web based apps now too. Check
this out:
Safari on iPhone, Mac OS X, and Windows all implement the Offline Web
Applications feature of HTML5. This feature allows you to cache all of
the resource files for your web application on the client, improving
the load time of your application and making it possible to create an
application which is fully functional even when there is no network
connection.

This is actually fulfilling a vision I expressed right here waaay back
in 2005:

Geez, It's like they've been working all this time for me entirely for
free ;)
Seriously, according to the news this week it now looks like most all
Smart Phone makers will adapt a similar, if not the same, approach to
web based apps that run on these devices.
Think about it, Apple knows that laptops and desktops need to be able
to run these same applications because it provides a fast and
inexpensive way for developers to integrate the use of these
applications with these different devices. Users want that, and they
want them to Feel like a native application too. Apple is essentially
giving them that.
So, looking forward it's easy to imagine that many Native apps will
really be Web Apps. The client side will contain the necessary tools
to run them. Updates and upgrades happen at the atomic level on the
server side and are instant and seamless and distributed as soon as the
software is accessed. (that's something I learned right here ;)
The advantages to developers both small and large are huge. I now
believe this is exactly where Apple is heading and as you can imagine,
I'm absolutely thrilled about it :)
