nothing is ever done off the cuff... even if Google would like to believe that it is.
I guess this is the way things go now in the corporate world. Jobs makes his leave of absence announcement on MLK day when the markets are closed in the U.S., and the next day (today, as I write this) Apple earnings for the last quarter are to be announced and are expected to be (among, at least) their best-ever. If that turns out to be the case, that will serve to tamp down and help recover any market losses due to Jobs' notice. Gotta love the forward-thinking that goes into this stuff.
