This news just confirms that Apple was right in ditching all other ports. In 2/3 years, anyone who bought an expensive computer with old ports will regret it
Not likely. I (like many others of whom I'm certain who bought a new MBP last year before the update) simply can't afford to get rid of all my older peripherals and replace them all at the same time. Like most other people, I'm sure I'll enjoy the new standard and will gradually replace things over time.
