I played around with it for a while this morning, having had trouble accessing it last night due to its overwhelming popularity. While Safari isn't supported, the app does work in Firefox and Camino, with a few UI glitches (widgets like scrollbars seem to be the biggest issue), but it's still amazingly solid and fast too, at least on my 2GHz MacBook.
Is it going to replace your current OS? No way. Not yet anyway. But anyone who can't hear Google's ears perking up isn't listening very hard. At the very least, one would hope these talented four guys will have jobs waiting for them by the time they leave school. And twenty years from now, who knows? We might all be using the great-great-great-great-grandchildren of YouOS everyday.
