Description: Microsoft Silverlight and Adobe Integrated Runtime (AIR) are RIA platforms that are usually compared to the capabilities of Ajax. Although this is a little bit unfair for these platforms because Ajax is a collection of web language and not a proprietary platform, Ajax has been heavily identified with Google especially with their release of Gears. Although Google Gears have been used by many and supported by most developers because of its open source persona, there are developers who have found Silverlight or AIR as their platform of choice. These two platforms (Silverlight and AIR) are constantly being compared especially on user experience. These platforms could provide RIA experience that’s almost unrivaled. The aesthetic experience of Microsoft and AIR is even better when you compare to most plug-ins powered by Google Gears.
