This is huge news and has the potential to change a lot of things. This "non-Apple" company has the potential to overtake a massive piece of the browser market, perhaps finally wresting control from IE.
Over time, the web is the direction everything has been going. Apple has been investing significantly in Safari and a establishing themselves to deliver web-apps like MobileMe.
Over time, many apps will be entirely web-based and platform independent.

I can see what Scooby is saying, but I am more on Arn's side here.
We are all speculating at this point, but the RIA market is growing very quickly and Adobe has recently (within the last 8 months) grabbed significant market share with Flex and AIR. Flex development is exploding rather quickly and as I am sure Adobe planned well in advance for this, their platform is already mature.
MS, Google and Apple are not going to sit on the sidelines and let Adobe take control of this rather lucrative vertical.
MS is working very hard with Silverlight and although is several major releases behind and lacking fundamental features, they are at least providing something for their developer base and promised features in the near future. They are not out of the fight, they have a large base of developers and a brand that will carry them.
Apple has their own proprietary markup language similar to Flex based on their Quicktime platform, and although it is internal and not published, we can probably expect something shortly from them.
Google is of course the one we do expect to be more interested in this area as they are working very hard to be king of browser applications.
This could be a significant change if they are more likely to deploy Chrome (mentioned earlier) more as a cross-platform runtime rather than just another browser.
I am not sure how they will compete or provide Google only features, but we'll see.
Maybe it's time for Google's G++, Objective-G or Gava. ;-)
