The usual reason given is convenience "I can get it all in 1 place, instead of driving/bussing around town looking for the local option". I am looking for a usb mic with a short wire to attach to my vr headset so I can stop killing peoples ears with hard P and similar. My local computer store doesn't carry any mics like I need only the desktop professional ones, nor any nearby local stores either. My only real option is to either go to Best Buy or Bozo. sigh
