I disagree... it's not about desktop vs. web, but rather native code vs. a teetering tower of questionably repurposed abstractions. No matter how fast WebKit becomes, it will still be a browser and will only offer a limited subset of what the hardware can really do. JIT compiling JavaScript engines and the various media specs in HTML 5 help, but there's still such a gulf.
