Jon Udell at InfoWorld - Application UI goes back to basics:
"As the new generation of so-called rich Internet clients arrives, let’s be careful what kind of richness we wish for. We don’t need Web recreations of the feature-bloated monsters that our office suites became. What we need instead, and what’s starting to appear, is a breed of lightweight single-purpose Web applications for basic tasks: writing, communicating, spreadsheeting, charting.
As the reaction to WriteRoom proves, there is enormous pent-up demand for applications that do one thing well."
