I'm curious which adapters everybody is talking about?
USB-C is very powerful and flexible when implemented properly. For instance when one buys a USB-C to lighting cable one can hook up iOS devices to the new MacBooks for syncing or charging but also use it's charger to charge it. Great for travel, bring one charger for both devices, charge them separately or daisy chain them and charge them both at the same time.
At home only a single USB-C cable is needed to power it while also hooking it up to a big screen, fixed network, harddrives, printers, etc. Yes one might need a USB-C hub (or screen with a builtin hub) for that but when thats sorted one has a very high speed docking station solution.
I will probably mis the SD card slot, simply cant remember the last time I've used a card reader. That said, how much longer is SD and it's current speed gonna stay the standard? Speeds increase every year, my 5 year old MBA takes for ever to download a 64GB card whereas a card reader built to the latest standards would be much faster and could cater all formats like CF, CF Fast, XQD, etc (for which people needed to bring a reader anyway).
For me personally a change to USB-C would mean I had to buy:
- USB-C to lighting cable for backing up and charging the iPhone (see second paragraph)
- USB-C to Micro USB to update my Sony's firmware and as a backup iPhone charging cable (combined with the little micro USB to lightening adapter I already have)
- USB-C to USB-A adapter for my other USB devices which use older standards like the label printer, old harddrives, etc
The first two will join me while travelling like their USB-A cousins are doing now so nothing changes here, the latter adapter is so tiny I might just tuck it in the camera bag anyway but there's no need to do so (other then enabling me to borrow other peoples USB-A cables or devices).
For travel the only major chance is that I need to bring a card reader again which I've been doing for years before switching to the Sony's so no big deal IMHO.
