While Vista doesn't crash with Flash on my system, Internet Explorer is
EXTREMELY unstable with Flash enabled. And even after updating to the latest
version today, it took under 5 minutes for it to crash again. So while it's
always good to have the most up-to-date software, Flash on Vista is flat-out
awful. Unfortunately, it's nearly impossible to browse the web these days
without running into a site that requires Flash.
Shame on web developers/advertisers for depending so much on Flash, shame on
Adobe for releasing something this unstable, and shame on Microsoft for
having a browser than can't gracefully host plug-ins.
