Relying on Forbes for technical information is akin to relying on Cat Fancy for geopolitics.
In this specific case, there was a flaw in OpenCORE, the PacketVideo open source multimedia framework, that was discovered. However, since the browser (or any app using OpenCORE) and OpenCORE run in separate processes as separate users, the OpenCORE flaw would, at most, affect the use of OpenCORE. This is not to say that the flaw was meaningless.
Is Android platform matured enough?
Compared to what?
How is the bug fixes & releases and forums support?
Right now, Android is averaging one patch release every two months, each containing bug fixes and new enhancements.
When I say matured, I'm referring to stability of the platform...
Oh, I understood that. But, I ask again: compared to what?
For example, some people consider Windows to be highly stable. Others think Windows is highly unstable.
I can tell you:
Android is layered atop of Linux and other components (e.g., WebKit) that get a fair amount of reuse and attention
Android runs all end-user apps in their own processes with their own user IDs (unless two such apps agree to share a user ID), to help isolate any security issues
On the other hand, Android is the first system to use the Dalvik VM and its associated class libraries
On the whole, I would expect Android to be more stable than Windows Mobile and Symbian. I would expect Android to be somewhat less stable than iPhone (simply because Android supports background processing, which iPhone does not). I lack enough knowledge of Blackberry to make a comparison there, and Palm WebOS is not yet available for comparison.
