What sucks is having a supercomputer in your jeans' pocket that is significantly less responsive to your input than a Commodore 64 and is mostly used to deliver ads to you.
I frequently have to pause while typing and wait for my pocket-supercomputer to catch up and actually give me feedback like putting text on the damn screen. Multi-second non-interactable pauses are not uncommon at all. If that isn't "unresponsive" I'd really like to know what is.
Yeah but that 300 baud modem is connected to another computer. I'm just typing on this somewhat laggy phone inside a textarea -- which while worse than a C64, isn't usually so bad that I regularly notice.
