well since you are arguing against flash let me try doing the same against unity

I never installed the plugin on any computer, never seen any realtime demos because I hate installing yet another plugin that possibly
- installes autostart stuff just like evil JRE, Acrobat,... and other annoying nagware
- propably wont run within my beloved Opera browser
- requires a decent GPU that is not present on my 4 years dated home PC, older notebook ect.
- is just good for 1 special eye-candy demo but not for +70% of the web I browse- why even install it then
- will slow down my computer if 8+ tabs are open with Unity3d stuff

and honestly I indeed never installed the plugin because of some of the reasons I guess I was not convinced enough so far same goes for silverlight. Once in a while booth are hyped and even $ms sponsers some developers to exclusivly develop with silverlight but in the end no consumer will care that hard because installing extra *free* stuff on the computer comes always with some little disadvantages like:
- autostart
- new myDocuments folder structure (e.g DivX movies with the DivX plugin, or Acrobat)
- additional adware toolbar gets installed (yahoo or google crap)
- installs extra software I never approved of (e.g Safari browser installes iTunes with the next update by default)
- a nag balloon in the system panel (next to the clock) appears every hour telling you there is new update available
- update services that try to get through your firewall to send computer and usage statistics and sometimes downloading updates with more crap features I did not wanted in the first place


he he I know I am a pain the ass with this,- but I just wanted to list some reasons why people like me or others sometimes dont wish to install something additional or experimental like unity_3d_activeX_plugin_xpVista.exe
