I normally carry a USB flash drive in my pocket. With the 
connector retracted, it is a bit less than 3 US nickels (2.25 
inches, 58mm) long. I would have no problem with either of the 
pictured devices.

A note in general. It is possible to make such devices too 
small. If I drop it and lose it on the floor, like I do with 
surface mounted electronic components, then it is, IMHO, too small.

Cheers - Bill
