The problem here is that 4G isn't a properly understood standard. When 2G phones came out, no one called them 2G, they just said they supported GPRS.
When 3G phones came out, they were clearly different from everything else, they were big and had lousy battery life. The LTE phones that have come out so far are nothing like this, they look and perform similarly to 3G phones.
For Apple this is just about advertising, it's not possible to look at the 4G label and decide what that means. I don't understand why Apple don't simply advertise the product as "80Mbps mobile data" or what ever speed the ipad can reach when it's sat next to an unused mobile cell.
The whole labelling things as 2G, 3G 20G etc. is stupid. It started off seeming like a good idea, but it very quickly gets out of hand. Much the same as the naming for USB, does anybody buy USB devices looking for ones that are super speed, hi-speed or full speed?
