The winner is Palm Pre SDK. Why? Palm picks a good architecture using javascript, html and css as its core technologies. There is little learning curve. Unlike iphone which you need to learn Objective-C, xcode, Cocoa, etc. It also follows convention over configuration (similar to rails). Using Eclipse as IDE is also a good choice. Using VirtualBox as the base of the Emulator is a very smart engineering choice. I like people who don’t reinventing the wheel. Setting up is esay and so is getting the helloworld app up. Good job Palm. I think you will have a good future in competing with Apple.
