Relative to herd flip flops, there should be little argument that there was plenty of bashing against screens bigger than 3.5" and then 4" before the herd believed Apple was going there. Then, when Apple did go there, the herd shifted right with them. Has Apple really been called out even with the 6? No, just a split of my iPhone is better than your iPhone because mine is bigger/smaller. What happened to 4" being perfection and everything bigger than that was "abominations", "99% don't want", etc? And I'm still to see any specially-made pants with bigger pockets in stores... or millions of men carry man purses because they can't fit the abomination in their pockets.
There were passionate arguments in support of Apple leaving the iSight camera out of an iPad 1 that largely evaporated into "shut up and take my money" when iPad 2 launched with FaceTime the standout hook. A camera made no sense when an iPad didn't have one but was the primary reason to upgrade when it was added.
There were passionate arguments about "720p being good enough" before Apple endorsed 1080p with

TV3. Prior, 1080p was a "gimmick", "no one could see the difference", "99%...", "the chart", "until the whole internet is able to stream 1080p", etc. Then, Apple goes there and nobody was faulting Apple for embracing the "gimmick". What happened to "the chart"? Did the whole internet get upgraded?
Over and over. This is just another round of the same. 2GB RAM in iDevices don't make sense today because Apple iDevices don't have 2GB RAM today. Per this rumor, in a few days Apple might roll out iDevices with 2GB RAM. If 2GB doesn't make sense today, it shouldn't make sense in a few days. But we know how that will play out.... the same way it always plays out.
