because usually the default SD reader pc are much slower, my UX31 well have a default drive, if I can and I instead I share with it, and the fact that it is usb3 more since I change my mobile phone by a S5 that it loads into usb3 too, so more than 1 cable walk.
yes it is small, but when you usually move several kilograms of camera gear, have a cable that has two functions is less painful than taking just one cable for that.
on the box it is given with a magnetized steel rests, but it is javoue gadget and I can never serves me, he would have had the base is heavier for it to be useful.
This player is also very useful because it also takes the MICRO SD, so perfect for the GoPro and other action cam, more needs to SD adapter ==> micro SD qu''on always ended up losing it is so small.
