I bought the Jobs bio yesterday when it hit the iTunes store in iBook form. About 1/4 of the way thru it now, it's a pretty good read actually, but does seem rushed in spots. Which can be expected since it wasn't supposed to come out until next year, so there's a bit of redundancy in the writing that's likely due to the rush deadline put on due to Jobs' passing away.
I was initially concerned it'd be censored to all hell to make the fellow seem like less of a cruel bugger, but the author was actually very forthright thus far on exactly what Jobs was like. I'd recommend it and it's sure to sell like gangbusters..
