You actually don't know my residential environment. I don't live in an apartment with 50 networks, but I can see ~30 SSID's right now. On a semi-regular basis I benefit from going into my router config to choose the channel with the least congestion. For me, that's not worth spending $$ to upgrade when speed & latency are not otherwise an issue. I don't begrudge people who decide to upgrade to get that incremental boost, but I don't think it should be forced on them. Because I'm not claiming there are no benefits to upgrading. I'm saying that people who have lived with their current WiFi setup-- hiccups & all-- for years shouldn't be required to pay more if they're satisfied with their own status quo.
