> People who have a bulky desktop computer in their home just to browse the internet are vanishingly few. 1. a PC isn't necessarily a "bulky desktop computer", it can also be a slimline laptop! 2. "browse the internet" and "office work/run a business/etc" are not mutually exclusive. Google Docs/Office 365 etc. proves that. I'd argue the majority of business operations requires some level of internet interaction these days. It seems to me like you've come up with a strawman definition to bat away another strawman definition. Almost everyone I know owns both a smartphone and a laptop, and the vast, vast majority of their time on that laptop is spent in a web browser.
