These tutorials pick up after you've completed the sample "Hello World" tutorial. After you complete the tutorial on the WebOS site, you should have a basic understanding of how an application is created for the Palm Pre. Unfortunately, you're then abandoned to read about the technical specs of widgets and other things. That's quite the jump in knowledge!
So, I've created some tutorials to hopefully build on your newly acquired knowledge to expand the app you started at the WebOS site.
Enyo Tutorial (The first place to start. On HP's developer site)
Extended Enyo Tutorial (The next place to go - Also on HP's developer site)
Mobile Tuts+ - Introduction to WebOS 3.0 (Enyo) (A good overview of creating Enyo apps)
WebOSSchool (A very good "course" on WebOS development - Free Registration Required)
Flickr Nearby SDK Experiment (Short tutorial using the GPS)
Linux Magazine - Using Lists in WebOS (A good overview of creating lists)
WebOS Boston - Basic WebOS Application and the Depot (A simple app that uses the Depot for storage)
WebOS Boston - Working with Cookies (Another demo showing how to store preferences in a cookie)
WebOS Internals (Great site for more than just development!)
Instructional for beginners (A PreCentral discussion/tutorial for those just starting)
Also, if you didn't know, Dropbox is a great tool for Windows, Mac, and Linux that helps you share and sync files between your computers. Here's my referral link, so you can sign up and install Dropbox! You will get 2.25 GB free, instead of 2 GB, for using a referral link.
