This is going to put companies like Dell in an awkward position. For the longest time people have been asking them to produce several universal PSUs, but instead at least in the consumer space they keep producing a new incompatible brick every year or so, now sometimes shipping with chips in them to assure nobody can make generic/compatible ones. So if USB-C laptop charging becomes popular, what will Dell do? Conform…
This is bound to happen, just like it happen for mobile phones (except iPhone).
What are you talking about? The iPhone uses standard USB chargers, and the only non-standard part (a USB-to-lightning cable) can be purchased from third party manufacturers for less than $10.
Yes you can find micro-USB cables for less than $2, but I don't mind because the utility of the connector outweighs the small price premium. What do Dell chargers do to deserve a premium price?
