I'm neither confused nor rolling my eyes. I like that Apple's principles have been understanding what people want and need, even when people SAY they want and need something else. People get fooled by marketing jargon all the time, people think that a device with 100 features MUST be better than a device with 50 features.
Apple understands what's actually important (mostly), and produces things that people will use effectively.
Now in terms of "Wifi + 4G", it really won't make any difference to people that the iPad isn't 4G. It's maximum speed is 42Mbps on Telstra 3G, with 6-18 Mbps being commonly reported. Our WiMax network (that is disappearing as it's rolling towards TDD-LTE) has historically been called "4G" too, but is slower than Telstra's latest 3G.
But the 4G term is very prominent in newspapers and marketing right now, being linked to the new networks here (in Australia) and never associated with DC-HSPA like AT&T is doing. I think Apple should use the terms commonly understood by consumers. And in fact they are not saying that DC-HSPA is 4G, they are saying the device IS 4G, just not Australian 4G. We're in Australia, so that's misleading.
