They lost me too with their "always connected to LTE". My 10" tablet does have a SIM card slot, so does my 6.5" phablet which I use as a small tablet. I don't have a SIM in either of those and I don't see the point. It's not like I use a laptop or a 10" tablet while I'm walking around outside. Cafe's have WIFI, trains have WIFI, buses have WIFI, I've got WIFI at home and every place I visit has WIFI.
I know Qualcomm is all about LTE always and everywhere (I've seen their presentations, I didn't get it then and I still don't). What, exactly, is the big advantage of using LTE if you have WIFI available? One transmits a very short distance and the other will transmit to something that's pretty far away.
I guess some will buy a device without WIFI but to me that's like trying to sell me a device without other essentials like a SD card slot and a headphone jack. I know some buy devices like that but to me it's like trying to sell me a car without a trunk because who needs that?
