Despite the title, the article doesn't talk about "iffy internet" at all. It's all about "slightly slow" internet which is a complete non-issue except for large downloads (e.g. modern games).

Congested and/or weak wifi and cell service are what "iffy" is about. Will a page _eventually_ load if I wait long enough? Or are there 10 sequential requests, 100KBs each, that all have succeed just to show me 2 sentences of text?
