I'd like a little more detail on what they mean by "flawlessly." It could be that Steve's idea of "flawlessly" involves things like being thrifty with battery-hogging system resources, playing nicely with the upcoming multi-tasking in 4.0, and having a culture around writing applications that feel "native" on their host platform.
There's nothing wrong with having a different definition of "flawlessly," I'm just wondering what Adobe means.
