It's unclear if the Samsung Nexus S will be a huge seller, but this particular version of it is definitely a huge device. It's a 42-inch version of the stock Android-powered "Google phone," with a multitouch screen, no less. The device passes all the processing to a real Samsung Nexus S.
The giant Nexus S, in a San Carlos, CA Best Buy, has a working camera, Internet access and Android 2.3 (Gingerbread). You can watch a video below and see all the huge action.
It's definitely not pocketable, not even like a Samsung Galaxy Tab.
