Yeah, nice 5G with huge speeds on cell phones that no one will actually use cause data caps are horrible and everyone waits to be home or on a WIFI to watch stuff like videos and do big downloads. So at the end of the day, 5G like 4G, 3G and 2G will be used for the same thing: Read emails and other text sources and send text messages...
(This rant is about mobile use in my country. I won't speak of other countries as I don't know what the deals are over there)
Yeah I did not think of portable gaming, but isn't 15mb/s enough for that? I think the bigger issue like everyone is saying, is unlimited data.
