Yeah I was puzzled by the claim “lawyers carry bags everywhere”. Maybe in 1980’s courtroom TV dramas they do.You know, things have evolved in the last 10-15 years...
Nobody I know wants to carry bags everywhere - wheeled or otherwise. How is that even relevant? So many people I know, myself included, work on the go. Often there is no permanent workspace with “ideal” (i.e., compromise-free) devices set up. You work where you find yourself and try to be as effective as you can - without schlepping a whole bagful of devices everywhere.
