That is fast for sure. However, I mean, fast is good but it gets to a point where fast enough is also good enough for me at least. I get about 20Mbps on home WiFi and maybe in the 20-35Mbps LTE in the Phoenix Metro area and that is way faster than I personally need or want. I used to have 5Mbps WiFi at home and that wasn't bad.
On the other side of things, I'm not a gamer nor do I d/l movies.
I personally don't know if I could tell a difference between 100 and 30 in my day to day ritual.
