For anyone who is on T-Mobile and gets throttled after they use their data limit. What is the real world experience? For example, is it essentially unusable or is it just noticeably slower but you are still able to be productive with it. I imagine video is out of the question, but does audio still stream at high speed since it doesn't count against your data cap anymore? How about web browsing or an online game like Words with Friends or Clash of Clans? Thanks for sharing your experiences.
