The announcement of the iPhone 4S is a good thing overall, even if yesterday's event was somewhat disappointing, analysts suggest. Sterne Agee's Shaw Wu remarks that many people were expecting an iPhone 5 with a larger screen and thinner shape. Needham's Charlie Wolf, by contrast, concentrates on the absence of an expected "iPhone Lite," even if Apple did drop the prices of older hardware. UBM TechInsights' VP of technical intelligence, David Carey, describes the 4S as a "modest technology bump," equivalent to the transition from the iPhone 3G to the 3GS.
