I personally think the throttling makes the phone pretty much unusable for anything but loading up a basic webpage or refreshing Facebook or Twitter. Any heavy webpage or trying to load up a YouTube video or Netflix takes forever and buffers constantly. I don't feel like I am able to use my phone to its fullest potential with reduced speeds.
Last bill cycle they throttled me at 11GB. That was with 10 days left to go in the bill cycle. I only managed to use another 2GB the remainder of the cycle and I was trying to use the phone the same way
Depends on what carriers throttling you're talking about.
On T Mobile is painful and very much useless cause they throttle it at 128 kbps speeds.
On AT&T its at 0.5mbps and with fast latency on LTE you can pretty much do everything from browsing, to audio and video streaming fine.
