Steve Jobs Hates Java, Gruber Agrees

On daringfireball
Jobs may well be spinning with his statements regarding third-party iPhone apps in general (and I hope he is), but his disdain for Java is completely straightforward. Java is no more relevant to iPhone app development than it is to Mac app development. iPhone apps are written in Cocoa and are designed specifically for the iPhone user interface. Cross-platform crippity-crap Java apps would stick out just as sorely on the iPhone as they do on the Mac.
(emphasis mine)
Crippity-crap Java Apps.
Sigh.
