Yeah, if one takes their work seriously, then a backup dongle is a must. I don’t travel much ever, yet I have a backup dongle sitting here just in case. $40 is much less expensive than loosing $40 and looking a fool because your clients can’t record because of a failed dongle thingy.
Try to explain that to someone paying much more per hour than the cost of a dongle and you can’t perform the work.
There is a great analogy in there I bet…
