Just like the iPhone, the iPad has never had naming conventions that have made much sense. The latest release just further confuses things:
- iPad 2
- The new iPad (with Retina display, 3rd generation)
- The new iPad (with Retina display, 4th generation)
- iPad Air
- iPad Air 2
Not confusing at all. And strangely seems to have just worked its way back to the original naming.
