Well, I really doubt (and hope) Flash support will be absent hitherto to today and from here on out. There are many political advantages to a Flashless internet and mobile device base, but there is also the video issue. WIFI already drags a fair bit on mobile phones, but as Daring Fireball pointed out, the Nexus One, which is supposed to catch 7 hours of video, drops to 3 when Flash is decoding H.264 video.
Hard to say really. The drop in battery time is significant, but while John Gruber reckons it is Flash, I reckon WiFi is doing most of it. Still, no flash is a good world. Of course, at the moment, HTML 5, the web standard can do pretty much all that Flash can, but lacks the dev tools to assist webmasters who aren't gifted in scripting and coding every little thing. For HTML 5.0 to assume its rightful place and proprietary tech to cool down, the masses need to be able to harness the power. When will that moment come?
