Cory Doctorow's Down and Out in the Magic Kingdom is a pretty good utopia. Also, I would happily live in the extreme post-singularity of complete AI control off all matter and energy from The Metamorphosis of Prime Intellect.
Doctorow's Utopia has few drawbacks that don't exist in modern society, and Metamorphosis is an issue of what friendly AI means. Eliezer, you'd probably like Metamorphosis if you haven't read it -- it's about an obscenely strong AI programmed to follow Asimov's three laws. It touches on a number of issues that you write about here, like orgasmium.
Both are available for free online, Doctorow's under a CC license and localroger's free as in beer.
