Windows 8 will not support
any plugins (including their own Silverlight) in lightweight "Metro" version, eg on tablets, mobile etc. So it's not about Flash. However Windows 8 for desktops will
fully support Flash.. And with new Flash 11 coming out soon Apple can shove their iOS because they will be left without all the cool things that Flash 11 brings with it such as really fast 3d rendering. Looks like the future of web is 3d after all.
PS. most Android devices run Flash no problem, so maybe it's not Flash that crashes iOS?
