How much do I really need? One person connecting to Wi-Fi and a laptop wired but rarely ever used. My biggest usage is Netflix and Amazon Prime Video. The biggest file I've downloaded in the last six months was Ubuntu. My browsing habits don't venture far from Reddit, Wikipedia, these forums, Craigslist, and academic research.
School, work, gym, and just about every other establishment I visit has WiFi.
What speed do I really need without throwing all my funbucks at an ISP?
