All-in-One PCs From Vizio, H.P. and Apple - State of the Art - NYTimes.com

Final paragraphs of a David Pogue all-in-one round-up

"All of these machines are successful in their goals. The iMac has the best screen you’ve ever seen on a computer, the finest craftsmanship and ridiculously fast response. The Vizio’s touch screen and low price give it a charm all its own. And the H.P. is competent, tidy and unimposing.
All of them represent ingenious steps forward in miniaturizing the innards of a computer. Each costs more than your standard plastic black box, of course. But sometimes, beauty, elegance and satisfaction are worth a few bucks."
