Just seen at London's Victoria station - a (Sandisk-branded) vending machine selling memory cards, phone acessories... and mobile broadband USB dongles. Shrink-wrapped, no cumbersome sales or registration process, no annoying salesperson trying to upsell you.
Just data connectivity, on a stick.
Like memory, on a stick.
Yes, there's still absolutely a role for contracts, retail stores, expert sales executives and so on. But solely going that route leaves money on the table when someone wants a quick transactional purchase. When I get to Victoria, I want to hail a taxi, not sign up for a cab account. Same thing for if I was dashing to catch a train and needed Internet connection for my trip.
