With Wallaby, Adobe is clearly readying itself for a “post-Flash” era that may be ushered in with the “post-PC” era.

Adobe needs to turn Flash into the webbook operating system of tomorrow, investing heavily in its performance and reliability and offering it as a framework solution to hardware vendors who use the Flash technology and tools to create a customized OS for their own touchscreen tablet devices, then in turn letting the existing installed base of Flash designers & Flash developers build apps for this new platform.
