I know there is a poll option but I want to actually hear reasoning and I'm less interested in the statistics this time. So very recently I heard a pretty good rant about adults who still carry backpack and the assertion we need to grow up and buy a damn briefcase already. As a long time technologist I could happily thumb my nose at them and continue carrying all my crap in a backpack. It's one of the perks of the job, people just assume you have little quirks and eccentricities and the thought of a 30+ year old still using a backpack is not really an issue. Sidenote, the last two companies I worked for would just issue whatever laptop bag their vendor provided, so a lot of people were carrying backpacks because that is what their computer came with. Recently though, my company issued backpack began to fall apart. It was actually for a previous employer so there will be no replacement. I'm pushing 40 hard (as in, I will turn 40 before 2013 is over) and while I still work in technology I am as high in management as you can get without actually being an executive. Which means I don't get the pass I used to for idiosyncrasies. So I decided to join the adult world and did actually purchase a briefcase. Not the traditional old-time leather ones like my Dad used to have but something that is a reasonable laptop bag that will also probably last forever and will travel well. Still, I'm wondering. Is this just hipster whining? Is it really a big deal that adult professionals will carry their stuff in a backpack these days?
