Flash was once upon a time, a nice small footprint tool...until Adobe bought it. Now it's as much of a pig, or more so, then a simple thing like Adobe Reader. Personally I have blocked Flash for a number of years now. Just say no to the plug-in by disabling it until there is a real need for it on a site I wish to use.

From what I have seen of Silverlight, it's OK...for now. Still not a fan of this sort of forced hardware overhead. For years my single biggest complaint about MS AND Apple is they force hardware upgrades by adding the bloat. This is to keep the ChipCo's happy just read up on the recent revelations about the emails between MS folks about how they bent over for Intel but hosed HP.

Sure nice shiny new things are pretty...but let's see it run first then decide. On my PC I have run into a couple sites that use Silverlight and recall they actually seemed fine. It's only once the parasitic AdCo's start pushing content we cannot stop/block w/o either a hassle or 3rd party plug-ins, then it will be time to blow off Silverlight.
