This is a baffling section where the author goes out of their way to bash browsers vs apps. Maybe there are a lot of cons to apps that browsers don't have. Basically all of the sleights against browsers in this section are not true. When I buy something from amazon, from my browser, I definitely do not need to manually enter my credit card in every time.
For me, iPhone feels like surfing the web with a 46kbauds modem. Single page at a time. Want to load two? IT RELOADS.
