The same could probably be said about extjs, too, but you'd find lots of intranet apps written in it -- often replacing predecessors written with Swing or even Tcl/Tk. Another popular approach here seems to be GWT. None of this is exactly "sexy" and blog-worthy, but neither are the POS and CRM apps themselves... And here I could see some inroads for Cappuccino, if it were targeted in that direction. Lots of companies are making their own business iOS applications, so having browser-based systems with a similar UX and API would be worth it. But to gain enterprise customers, you'd probably need more marketing in that direction and paid support.
