As a developer I like that I can use the API now instead of just reading about it. Chrome rolls out updates very smoothly and rapidly, who cares if the initial support of a very new standard is not perfect? It sure beats the support that FireFox, IE and Safari have (none).
For this particular feature; there are plenty that Chrome doesn't support fully (IndexedDB) or at all (CSS calc) that those other browsers have had for quite a long time.
