If I'm not mistaken arent they able to install 4G technology on all their preexisting 3G towers? Or are the laws/rights not actually governed by physical tower infrastructure but rather "air space" of 4G frequencies... or some bs like that?
Probably, but there's still a finite number of towers they can get up in a given area. But even if LTE has 10X the capacity of 3G (just based on throughput, and probably more than that), you can see a problem with usage going from 2gigs to 30gigs (or 100).
Netflix and other video gets further compressed going to a smartphone. From that perspective, it would be really tough to burn thru 10 gigs (without torrents). But I don't want to HDMI out compressed video to a 50" plasma. And if I tether a computer or PS3 I would guess it doesn't d/l as compressed of video.
480p is fine for a phone, but it's gotta be 720 for tablets...and so, what, 3 movies and you're done, no more HD video for the month?
