I tried it today. I don't like the interface and that you can't choose where to install it. Actually I hate that with applications :/
But I like how fast it is. It starts fast and it loads pages fast.

In comparison to Safari it's the better choice for Webkit browsers on Windows, I suppose. Safari takes forever just to start up. Also, it doesn't make use of Mac OS X's font rendering and it might just be my imagination, but it seems a tad faster too.

Wait, just checked again, some pages seem to be slower on Chrome than on Safari. Weird.
