Re: Getting rid of Magsafe was a mistake
At a minimum, if Apple was going to compromise so drastically as to only have one USB port they should have at the least included an extra on the power adapter.
I'm pretty sure it's exactly Apple's business model to charge a large wedge of cash for the 'official' adaptor in such situations, and to design it to have a limited life, so they get the repeat business. After all, they have a long history of using non industry-standard ports and connectors entirely so that they can charge extra for cables.
The new iPhones have a socket which looks superficially like a micro-USB (which every other phone on the market uses), but which require a proprietary connector.
This goes all the way back to the old Macintosh computers with SCSI ports which had the same connectors as standard parallel ports, but were utterly incompatible, in some cases damaging hardware that was plugged into the wrong type of port.
