Thinking out-of-the-box for a moment, Palm would be a good acquisition target for Adobe. The Mojo SDK could certainly use the Adobe expertise in web-based development tools. Alone, Palm really doesn't have a chance of catching up with Apple.
Unfortunately, the Palm "App Store" will not be available until fall:
Thousands of developers have participated in the Mojo SDK early access program since it began in early April. New applications are in the pipeline for the Palm App Catalog, and the App Catalog submission process will be opened to all developers beginning this fall.
