I finished reading Cory Doctorow's Down and Out in the Magic Kingdom. Not awful, but not so great. It mostly seems to adopt some props from Egan's Permutation City with a bit of Vinge's Marooned in Realtime, but it doesn't do anything clever with those props. The prose is overdetermined. Read Bruce Sterling instead. Or the paper. Or take a nap. Mmmmm nap.
It's not a bad first try tho. At least he remembered to have a real plot -- something which regularly escapes some people (ahem Stephenson, Egan, etc etc).
