What? Your argument is flawed. The iPad 2 is still a functional device. In fact, it runs certain apps better than the iPad 3.
The iPad 3 was Apple being desperate. The A5X chip was never sufficient to drive the Retina screen. In certain cases the iPad 2 actually performed better.
I rushed out and got an iPad 3 due to Retina. That being said, I still think the iPad 2 is a more useful and better product overall. Apple should have waited to introduce Retina until iPad 4 so that the chip would actually be good enough for the screen.
