Appcelerator has more than 19000 developers using its tool to create cross-platform applications including mobile apps on iphone and Android platform and it, tonight, is announcing Apple Tablet support (more details will come out Thursday after Apple makes its announcement). Here I interview Jeff Haynie, CEO of Appcelerator, about that. How can they do that? Well, they are supporting the iphone OS 4.0, which will have support for Apple’s new Tablet. What is Appcelerator’s developer tool aimed at? Getting web developers to build first-rate native applications on all these platforms (it’s really a competitor of Adobe AIR). You can see demos of their current tool and API at www.appcelerator.com
