In what has to be the biggest load of crap I have ever read online, TechCruch's Michael Arrington says that Silverlight makes Flash and Flex look like a toy. I think that Michael is jumping the gun a little bit here by saying this about Silverlight. Silverlight has yet to be released as a full product and it has yet to be adopted by any web users.
That being said Flash enjoys a 98% penetration rate. A penetration rate that has seen competing technologies go down in flames. For one I remember all the hype over "Microsoft's Sparkle" and it being a Flash killer. Where is that product now exactly??
Now in with Flash and FP9 the features are growing more and more. The acquisition of Macromedia by Adobe has made the product grow by leaps and bounds. All of this combined with the penetration rate will see Flash stay around for many many more years.
As soon as Silverlight hits a 97% penetration rate, give me a call. Till then Flash is King. But what happens when Silverlight fails? Will Microsoft start looking at buying Adobe?
