Whether or not you can derive value from the Air at work depends on how loud you can play it, how you place it and whether you have access to wifi.
I don't think I'll have trouble deriving value from it. No matter what, it will play cleanly louder than the existing Bluetooth speaker. For my personal use, I'd hook my phone up via the analog connection and play music that's stored on the phone with MediaMonkey. I'm on night shift now, alone for 6-7 hours of it, so I won't be bothering anyone else with my music. The only thing that gives me pause is I'd want to be a good guy and let other people use it during the day when I'm not there. If the wireless connectivity is flaky, I'll probably just put it in my locker when I'm not there.
