Ethernet, a couple times a month when hotel wifi sucks.
HDMI every single day to connect my 13 to my monitor, and a couple times a month for customer monitors
Mini DisplayPort every day to connect my 15 to my monitor
VGA couple times a week to connect to customer projectors
DVI once every couple of months to connect to a customer adapter
USB-a x4 to connect iTunes library, backup drives, iOS devices, and external storage to the macs, including portable hard drives to store and backup 200-400gb of photos while on a shoot
Sd card, hardly ever as I use cf most of the time.
I'm looking at a minimum of 6 dongles in my bag. HDMI, Mini DisplayPort, and USB-a are the new ones.
It's a transition, and it sucks. But that would have been fine if the darned adapters were available, worked properly, and weren't another couple hundred bucks on top of a price increase for a mediocre set of improvements.
