This article from Nick Kolakowski highlights the developer sentiment, causing a 185% usage of the Apple development kit and related tools since announcing the iPad emulator.
Objective-C is a language steeped in Apple lore, starting back in the 1980’s and has ties to C, Smalltalk and arguably has some Visual Basic event-driven cues in its modern iteration and use with Cocoa.
